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 when SELV is exceeded 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 Hipot test, flash-tested, withstand voltage, proof voltage, dielectric withstand voltage, and isolation test voltage are all terms that relate to the same thing: 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 DCP02 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 DCP02 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.

The DCP02 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 DCP02-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 SYNC pin low. When the SYNC pin goes low, the output pins transition into tri-state mode, which occurs within 2 μs. 8.3.4 Thermal Shutdown The DCP02 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. 8.3.5 Synchronization In the event that 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 DCP02 series of devices overcome this interference by allowing devices to be synchronized to one another. Up to eight devices can be synchronized by connecting the SYNC pins together, taking care to minimize the capacitance of tracking. Stray capacitance (greater than 3 pF) has the effect of reducing the switching frequency, or even stopping 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's input pin. 8.3.6 Construction The basic construction of the DCP02 series of devices is the same as standard integrated circuits. The molded package contains no substrate. The DCP02 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 this device, it is advisable to provide ground planes on the input and output. 10 Submit Documentation Feedback Copyright © 2000–2015, Texas Instruments Incorporated Product Folder Links: DCP020503 DCP020505 DCP020507 DCP020509 DCP020515D DCP021205 DCP021212 DCP021212D DCP021515 DCP022405 DCP022405D DCP022415D DCP020503, DCP020505, DCP020507, DCP020509, DCP020515D, DCP021205 DCP021212, DCP021212D, DCP021515, DCP022405, DCP022405D, DCP022415D www.ti.com SBVS011L – MARCH 2000 – REVISED MAY 2015 8.4 Device Functional Modes 8.4.1 Disable/Enable (SYNC pin) Any of the DCP02 series devices can be disabled or enabled by driving the SYNC pin using an open drain CMOS gate. If the SYNC pin is pulled low, the DCP02 becomes disabled. The disable time depends upon the external loading. The internal disable function is implemented in 2 μs. Removal of the pull down causes the DCP02 to be enabled. Capacitive loading on the SYNC 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/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. A 2.2-μF capacitor on the input is also recommended. 8.4.2.2 Connecting the DCP02 in Series Multiple DCP02 isolated 2W 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 DCP02. Connect the +VOUT from one DCP02 to the –VOUT of another (see Figure 9). If the SYNC pins are tied together, the self-synchronization feature of the DCP02 prevents beat frequencies on the voltage rails. The SYNC feature of the DCP02 allows easy series connection without external filtering, thus minimizing cost. The outputs of a dual-output DCP02 can also be connected in series to provide two times the magnitude of VOUT, as shown in Figure 10. For example, connect a dual-output, 15-V, DCP022415D device to provide a 30-V rail. All 5-V, 12-V, and 15-V input voltage designs require a2.2-μF, low-ESR ceramic input capacitor, while 24-V input applications require only 0.47 μF of input capacitance.

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; devices must not be connected in series, as this will cascade 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 ( ) 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 15). In Figure 15, XC is the reactance due to the capacitance, XL 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. Z XC XL 0 Frequency (Hz) f0 Figure 15. Capacitor Impedance vs Frequency At f0, XC = XL; 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 be well above the 800-kHz switching frequency of the DCP and DCVs. 14 Submit Documentation Feedback Copyright © 2000–2015, Texas Instruments Incorporated Product Folder Links: DCP020503 DCP020505 DCP020507 DCP020509 DCP020515D DCP021205 DCP021212 DCP021212D DCP021515 DCP022405 DCP022405D DCP022415D DCP020503, DCP020505, DCP020507, DCP020509, DCP020515D, DCP021205 DCP021212, DCP021212D, DCP021515, DCP022405, DCP022405D, DCP022415D www.ti.com SBVS011L – MARCH 2000 – REVISED MAY 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 1. 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 (1) 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 the 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 a good startup performance. For 24V 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.

Repeating the above calculations using the 100% load resistance of 25 Ω (0.2 A per output), the results are: τ = 25 μs tDIS = 1.25 μs VDIS = 244 mV VESR = 20 mV Ripple Voltage = 266 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 = 45 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 DCP02 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 DCP02. If this connection is not possible, then the supplies must be connected in a star formation with the traces made as wide as possible. 16 Submit Documentation Feedback Copyright © 2000–2015, Texas Instruments Incorporated Product Folder Links: DCP020503 DCP020505 DCP020507 DCP020509 DCP020515D DCP021205 DCP021212 DCP021212D DCP021515 DCP022405 DCP022405D DCP022415D DCP020503, DCP020505, DCP020507, DCP020509, DCP020515D, DCP021205 DCP021212, DCP021212D, DCP021515, DCP022405, DCP022405D, DCP022415D www.ti.com SBVS011L – MARCH 2000 – REVISED MAY 2015 11 Layout 11.1 Layout Guidelines Due to the high power density of these devices, provide ground planes on the input and output. Figure 19 and Figure 17 illustrate a printed circuit board (PCB) layout for the two conventional (DCP01/02, DCV01), and two SOP surface-mount packages (DCP02U). Figure 16 shows the schematic. 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. 11.2 Layout Example CON1 VS1 1 +VS SYNC 14 CON3 JP1 VS3 1 C1 +VS SYNC 28 JP1 C11 NC 27 0V1 2 0V3 –VS DCP02xxxxP +V1 6 C3 C2-1 +VOUT +V3 C2 –VS 3 –VS C12 R5 5 COM1 C5 C4-1 NC 26 13 +VOUT C13 R1 2 DCP02xxxxU COM 12 COM C4 COM3 C14 R2 C15 R6 – V1 7 –VOUT – V3 14 –VOUT CON2 VS2 1 +VS SYNC 14 CON4 JP2 VS4 1 C6 +VS SYNC 28 JP2 C16 NC 27 0V2 2 –VS 0V4 DCP02xxxxP +V2 6 C8 C7-1 +VOUT C7 +V4 COM2 C10 C9-1 12 COM COM4 R4 – V2 –VS DCP02xxxxU COM C9 3 NC 26 C18 R7 5 –VS 13 +VOUT C17 R3 2 C20 C19 R8 7 –VOUT Figure 16.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) 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. (4) 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.
