8 Detailed Description
8.1 Overview
The DCP01B offers up to 1 W of isolated, unregulated output power from a 5-V, 15-V, or 24-V input source with
a typical efficiency of up to 85%. This efficiency is achieved through highly integrated packaging technology and
the implementation of a custom power stage and control device. The DCP01 devices are specified for
operational isolation only. The circuit design uses an advanced BiCMOS and DMOS process.

SBVS012F – DECEMBER 2000 – REVISED OCTOBER 2015
8.3 Feature Description
8.3.1 Isolation
Underwriters Laboratories, UL™ defines several classes of isolation that are used in modern power supplies.
Safety extra low voltage (SELV) is defined by UL (UL1950 E199929) as a secondary circuit which is so
designated and protected that under normal and single fault conditions the voltage between any two accessible
parts, or between an accessible part and the equipment earthing terminal for operational isolation does not
exceed steady state 42 V peak or 60 VDC for more than 1 second.
8.3.1.1 Operation or Functional Isolation
Operational or functional isolation is defined by the use of a high-potential (hipot) test only. Typically, this
isolation is defined as the use of insulated wire in the construction of the transformer as the primary isolation
barrier. The hipot one-second duration test (dielectric voltage, withstand test) is a production test used to verify
that the isolation barrier is functioning. Products with operational isolation should never be used as an element in
a safety-isolation system.
8.3.1.2 Basic or Enhanced Isolation
Basic or enhanced isolation is defined by specified creepage and clearance limits between the primary and
secondary circuits of the power supply. Basic isolation is the use of an isolation barrier in addition to the insulated
wire in the construction of the transformer. Input and output circuits must also be physically separated by
specified distances.
8.3.1.3 Continuous Voltage
For a device that has no specific safety agency approvals (operational isolation), the continuous voltage that can
be applied across the part in normal operation is less than 42.4 VRMS, or 60 VDC. Ensure that both input and
output voltages maintain normal SELV limits. The isolation test voltage represents a measure of immunity to
transient voltages.
WARNING
Do not use the device as an element of a safety isolation system that exceeds
the SELV limit.
If the device is expected to function correctly with more than 42.4 VRMS or 60 VDC applied continuously across the
isolation barrier, then the circuitry on both sides of the barrier must be regarded as operating at an unsafe
voltage, and further isolation or insulation systems must form a barrier between these circuits and any useraccessible circuitry according to safety standard requirements.
8.3.1.4 Isolation Voltage
The terms Hipot test, flash-tested, withstand voltage, proof voltage, dielectric withstand voltage, and isolation test
voltage are describe a similar idea. They describe a test voltage applied for a specified time across a component
designed to provide electrical isolation to verify the integrity of that isolation. TI’s DCP01B series of dc-dc
converters are all 100% production tested at 1.0 kVAC for one second.
8.3.1.5 Repeated High-Voltage Isolation Testing
Repeated high-voltage isolation testing of a barrier component can degrade the isolation capability, depending on
materials, construction, and environment. The DCP01B series of dc-dc converters have toroidal, enameled, wire
isolation transformers with no additional insulation between the primary and secondary windings. While a device
can be expected to withstand several times the stated test voltage, the isolation capability depends on the wire
insulation. Any material, including this enamel (typically polyurethane), is susceptible to eventual chemical
degradation when subject to very-high applied voltages. Therefore, strictly limit the number of high-voltage tests
and repeated high-voltage isolation testing. However, if it is absolutely required, reduce the voltage by 20% from
specified test voltage with a duration limit of one second per test.

Feature Description (continued)
8.3.2 Power Stage
The DCP01B series of devices uses a push-pull, center-tapped topology. The DCP01B devices switch at 400
kHz (divide-by-2 from an 800-kHz oscillator).
8.3.3 Oscillator And Watchdog Circuit
The onboard, 800-kHz oscillator generates the switching frequency via a divide-by-2 circuit. The oscillator can be
synchronized to other DCP01B series device circuits or an external source, and is used to minimize system
noise.
A watchdog circuit checks the operation of the oscillator circuit. The oscillator can be disabled by pulling the
SYNCIN pin low. When the SYNCIN pin goes low, the output pins transition into tri-state mode, which occurs
within 2 μs.
8.3.4 Thermal Shutdown
The DCP01B series of devices are protected by a thermal-shutdown circuit.
If the on-chip temperature rises above 150°C, the device shuts down. Normal operation resumes as soon as the
temperature falls below 150°C. While the overtemperature condition continues, operation randomly cycles on and
off. This cycling continues until the temperature is reduced.
8.3.5 Synchronization
When more than one DC/DC converter is needed onboard, beat frequencies and other electrical interference can
be generated. This interference occurs because of the small variations in switching frequencies between the
DC/DC converters.
The DCP01B series of devices overcomes this interference by allowing devices to synchronize to one another.
Synchronize up to eight devices by connecting the SYNC pins of each device, taking care to minimize the
capacitance of tracking. Stray capacitance (greater than 3 pF) reduces the switching frequency, or can
sometimes stop the oscillator circuit. The maximum recommended voltage applied to the SYNC pin is 3.0 V.
For an application that uses more than eight synchronized devices use an external device to drive the SYNC
pins. The application report External Synchronization of the DCP01/02 Series of DC/DC Converters (SBAA035)
describes this configuration.
NOTE
During the start-up period, all synchronized devices draw maximum current from
the input simultaneously. If the input voltage falls below approximately 4 V, the
devices may not start up. A 2.2-μF capacitor should be connected close to each
device input pin.
8.3.6 Construction
The basic construction of the DCP01B series of devices is the same as standard integrated circuits. The molded
package contains no substrate. The DCP01B series of devices are constructed using an IC, rectifier diodes, and
a wound magnetic toroid on a leadframe. Because the package contains no solder, the devices do not require
any special printed circuit board (PCB) assembly processing. This architecture results in an isolated DC/DC
converter with inherently high reliability.
8.3.7 Thermal Management
Due to the high power density of these devices, it is advisable to provide ground planes on the input and output
rails.

8.4 Device Functional Modes
8.4.1 Disable and Enable (SYNCIN pin)
Each of the DCP01B series devices can be disabled or enabled by driving the SYNCIN pin using an open drain
CMOS gate. If the SYNCIN pin is pulled low, the DCP01B becomes disabled. The disable time depends upon the
external loading. The internal disable function is implemented within 2 μs. Removal of the pull down causes the
DCP01B to be enabled.
Capacitive loading on the SYNCIN pin should be minimized (≤ 3 pF) in order to prevent a reduction in the
oscillator frequency. The application report External Synchronization of the DCP01/02 Series of DC/DC
Converters (SBAA035) describes disable and enable control circuitry.
8.4.2 Decoupling
8.4.2.1 Ripple Reduction
The high switching frequency of 400 kHz allows simple filtering. To reduce ripple, it is recommended that a
minimum of 1-μF capacitor be used on the +VOUT pin. For dual output devices, decouple both of the outputs to
the COM pin. The required 2.2-μF, low ESR ceramic input capacitor also helps to reduce ripple and noise, (24-V
input voltage versions require only 0.47 µF of input capacitance). See DC-to-DC Converter Noise Reduction
(SBVA012).
8.4.2.2 Connecting the DCP01B in Series
Multiple DCP01B isolated 1-W DC/DC converters can be connected in series to provide non-standard voltage
rails. This configuration is possible by using the floating outputs provided by the galvanic isolation of the DCP01.
Connect the +VOUT from one DCP01B to the –VOUT of another (see Figure 29). If the SYNCIN pins are tied
together, the self-synchronization feature of the DCP01B prevents beat frequencies on the voltage rails. The
synchronization feature of the DCP01B allows easy series connection without external filtering, thus minimizing
cost.

9.2.3 Detailed Design Procedure
9.2.3.1 Input Capacitor
For all 5-V and 15-V input voltage designs, select a 2.2-μF low-ESR ceramic input capacitor to ensure a good
startup performance. 24-V input applications require only 0.47-μF of input capacitance.
9.2.3.2 Output Capacitor
For any DCP01B design, select a 1.0-μF low-ESR ceramic output capacitor to reduce output ripple.
9.2.3.3 SYNCIN Pin
In a stand-alone application, leave the SYNCIN pin floating.
9.2.4 PCB Design
The copper losses (resistance and inductance) can be minimized by the use of mutual ground and power planes
(tracks) where possible. If that is not possible, use wide tracks to reduce the losses. If several devices are being
powered from a common power source, a star-connected system for the track must be deployed. Do not connect
the devices in series, because that type of connection cascades the resistive losses. The position of the
decoupling capacitors is important. They must be as close to the devices as possible in order to reduce losses.
See the PCB Layout section for more details.
9.2.5 Decoupling Ceramic Capacitors
Capacitor Impedance (Ÿ )
All capacitors have losses because of internal equivalent series resistance (ESR), and to a lesser degree,
equivalent series inductance (ESL). Values for ESL are not always easy to obtain. However, some
manufacturers provide graphs of frequency versus capacitor impedance. These graphs typically show the
capacitor impedance falling as frequency is increased (as shown in Figure 35). In Figure 35, XC is the reactance
due to the capacitance, X L is the reactance due to the ESL, and f0 is the resonant frequency. As the frequency
increases, the impedance stops decreasing and begins to rise. The point of minimum impedance indicates the
resonant frequency of the capacitor. This frequency is where the components of capacitance and inductance
reactance are of equal magnitude. Beyond this point, the capacitor is not effective as a capacitor.

However, there is a 180° phase difference resulting in cancellation of the imaginary component. The resulting
effect is that the impedance at the resonant point is the real part of the complex impedance, namely, the value of
the ESR. The resonant frequency must much higher than the 800-kHz switching frequency of the device.

SBVS012F – DECEMBER 2000 – REVISED OCTOBER 2015
The effect of the ESR is to cause a voltage drop within the capacitor. The value of this voltage drop is simply the
product of the ESR and the transient load current, as shown in Equation 2.
VIN = VPK – (ESR × ITR)
where
•
•
•
VIN is the voltage at the device input
VPK is the maximum value of the voltage on the capacitor during charge
ITR is the transient load current
(2)
The other factor that affects the performance is the value of the capacitance. However, for the input and the full
wave outputs (single-output voltage devices), ESR is the dominant factor.
9.2.6 Input Capacitor and the Effects of ESR
If the input decoupling capacitor is not ceramic (and has an ESR greater than 20 mΩ), then at the instant the
power transistors switch on, the voltage at the input pins falls momentarily. If the voltage falls below
approximately 4 V, the DCP detects an undervoltage condition and switches the DCP drive circuits to a
momentart off state. This detection is carried out as a precaution against a genuine low input voltage condition
that could slow down or even stop the internal circuits from operating correctly. A slow-down or stoppage results
in the drive transistors being turned on too long, causing saturation of the transformer and destruction of the
device.
Following detection of a low input voltage condition, the device switches off the internal drive circuits until the
input voltage returns to a safe value, at which time the device tries to restart. If the input capacitor is still unable
to maintain the input voltage, shutdown recurs. This process repeats until the input capacitor charges sufficiently
to start the device correctly.
Normal startup should occur in approximately 1 ms after power is applied to the device. If a considerably longer
startup duration time is encountered, it is likely that either (or both) the input supply or the capacitors are not
performing adequately.
For 5-V to 15-V input devices, a 2.2-μF, low-ESR ceramic capacitor ensures good startup performance. For 24-V
input voltage devices, 0.47 μF ceramic capacitors are recommended. Tantalum capacitors are not
recommended, since most do not have low-ESR values and will degrade performance. If tantalum capacitors
must be used, close attention must be paid to both the ESR and voltage as derated by the vendor.
NOTE
During the start-up period, these devices may draw maximum current from the input
supply. If the input voltage falls below approximately 4 V, the devices may not start
up. Connect a 2.2-μF ceramic capacitor close to the input pins.
9.2.7 Ripple and Noise
A good quality, low-ESR ceramic capacitor placed as close as practical across the input reduces reflected ripple
and ensures a smooth startup.
A good quality, low-ESR ceramic capacitor placed as close as practical across the rectifier output terminal and
output ground gives the best ripple and noise performance. See DC-to-DC Converter Noise Reduction
(SBVA012), for more information on noise rejection.
9.2.7.1 Output Ripple Calculation Example
The following example shows that increasing the capacitance has a much smaller effect on the output ripple
voltage than does reducing the value of the ESR for the filter capacitor.

tDIS = 0.0125 μs
τ = C × RLOAD
τ = 1 × 10-6 × 12.5 = 12.5 μs
VDIS = VO(1 – EXP(–tDIS/τ))
VDIS = 5 mV
By contrast, the voltage dropped because of ESR:
VESR = ILOAD × ESR
VESR = 20 mV
Ripple voltage = 25 mV
9.2.8 Dual DCP01B Output Voltage
The voltage output for dual DCP01B devices is half wave rectified; therefore, the discharge time is 1.25 μs.
Repeating the above calculations using the 100% load resistance of 50 Ω (0.1 A per output), the results are:
τ = 25 μs
tDIS = 1.25 μs
VDIS = 244 mV
VESR = 10 mV
Ripple Voltage = 133 mV
This time, it is the capacitor discharging that contributes to the largest component of ripple. Changing the output
filter to 10 μF, and repeating the calculations, the result is:
Ripple Voltage = 25 mV.
This value is composed of almost equal components.
The previous calculations are offered as a guideline only. Capacitor parameters usually have large tolerances
and can be susceptible to environmental conditions.
9.2.9 Optimizing Performance
Optimum performance can only be achieved if the device is correctly supported. The very nature of a switching
converter requires power to be instantly available when it switches on. If the converter has DMOS switching
transistors, the fast edges will create a high current demand on the input supply. This transient load placed on
the input is supplied by the external input decoupling capacitor, thus maintaining the input voltage. Therefore, the
input supply does not see this transient (this is an analogy to high-speed digital circuits). The positioning of the
capacitor is critical and must be placed as close as possible to the input pins and connected via a low-impedance
path.
The optimum performance primarily depends on two factors:
• Connection of the input and output circuits for minimal loss.
• The ability of the decoupling capacitors to maintain the input and output voltages at a constant level.
10 Power Supply Recommendations
The DCP01B is a switching power supply, and as such can place high peak current demands on the input
supply. In order to avoid the supply falling momentarily during the fast switching pulses, ground and power
planes should be used to connect the power to the input of DCP01 device. If this connection is not possible, then
the supplies must be connected in a star formation with the traces made as wide as possible.

11 Layout
11.1 Layout Guidelines
Due to the high power density of these devices, provide ground planes on the input and output rails.
Figure 36 and Figure 37 show the schematic for the two DIP through-hole packages, and two SOP surfacemount packages for the DCP family of products which include DCP01B, DCP02, DCV01, DCR01, and DCR02.
Figure 38 and Figure 39 illustrate a printed circuit board (PCB) layout for the schematics.
Including input power and ground planes provides a low-impedance path for the input power. For the output, the
COM signal connects via a ground plane, while the connections for the positive and negative voltage outputs
conduct via wide traces in order to minimize losses.
The output should be taken from the device using ground and power planes, thereby ensuring minimum losses.
The location of the decoupling capacitors in close proximity to their respective pins ensures low losses due to the
effects of stray inductance, thus improving the ripple performance. This location is of particular importance to the
input decoupling capacitor, because this capacitor supplies the transient current associated with the fast
switching waveforms of the power drive circuits.
Allow the unused SYNC pin, to remain configured as a floating pad. It is advisable to place a guard ring
(connected to input ground) or annulus connected around this pin to avoid any noise pick up. When connecting a
SYNC pin to one or more SYNC design the linking trace to be short and narrow to avoid stray capacitance.
Ensure that no other trace is in close proximity to this trace SYNC trace to decrease the stray capacitance on
this pin. The stray capacitance affects the performance of the oscillator.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability
information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)
(3)
MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.

There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.
(5)
Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation
of the previous line and the two combined represent the entire Device Marking for that device.
(6)
Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish
value exceeds the maximum column width.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
