•
The LM5007 Step Down Switching Regulator features
all of the functions needed to implement low cost,
efficient, Buck bias regulators. This high voltage
regulator contains an 80 V, 0.7A N-Channel Buck
Switch. The device is easy to apply and is provided in
the VSSOP-8 and the thermally enhanced WSON-8
packages. The regulator is based on a hysteretic
control scheme using an on time inversely
proportional to VIN. This feature allows the operating
frequency to remain relatively constant with load and
input voltage variations. The hysteretic control
requires no control loop compensation, while
providing very fast load transient response. An
intelligent current limit is implemented in the LM5007
with forced off time that is inversely proportional to
VOUT. This current limiting scheme reduces load
current foldback. Additional protection features
include: Thermal Shutdown, Vcc undervoltage
lockout, gate drive undervoltage lockout, and Max
Duty Cycle limiter.

DETAILED OPERATING DESCRIPTION
The LM5007 Step Down Switching Regulator features all of the functions needed to implement low cost, efficient,
Buck bias regulators. This high voltage regulator contains an 80V, 0.7A N-Channel Buck Switch. The device is
easy to apply and is provided in the VSSOP-8 and the thermally enhanced WSON-8 packages. The regulator is
based on a hysteretic control scheme using an on time inversely proportional to Vin. This feature allows the
operating frequency to remain relatively constant with load and input voltage variations. The hysteretic control
requires no control loop compensation, while providing very fast load transient response. An intelligent current
limit scheme is implemented in the LM5007 with forced off time, after current limit detection, which is inversely
proportional to Vout. This current limiting scheme reduces load current foldback. Additional protection features
include: Thermal Shutdown, Vcc undervoltage lockout, Gate drive undervoltage lockout and Max Duty Cycle
limiter. The LM5007 can be applied in numerous applications to efficiently regulate step down higher voltage
inputs. This regulator is well suited for 48 Volt Telcom and the new 42V Automotive power bus ranges.
Hysteretic Control Circuit Overview
The LM5007 is a Buck DC-DC regulator that uses an on time control scheme. The on time is programmed by an
external resistor and varies inversely with line input voltage (Vin). The core regulation elements of the LM5007
are the feedback comparator and the on time one-shot. The regulator output voltage is sensed at the feedback
pin (FB) and is compared to an internal reference voltage (2.5V). If the FB signal is below the reference voltage,
the buck switch is turned on for a fixed time pulse determined by the line voltage and a programming resistor
(RON). Following the on period the switch will remain off for at least the minimum off timer period of 300ns. If the
FB pin voltage is still below the reference after the 300ns off time, the switch will turn on again for another on
time period. This switching behavior will continue until the FB pin voltage reaches the reference voltage level.
The LM5007 operates in discontinuous conduction mode at light load currents or continuous conduction mode at
heavier load currents. In discontinuous conduction mode, current through the output inductor starts at zero and
ramps up to a peak value during the buck switch on time and then back to zero during the off time. The inductor
current remains at zero until the next on time period starts when FB falls below the internal reference. In
discontinuous mode the operating frequency can be relatively low and will vary with load. Therefore at light loads
the conversion efficiency is maintained, since the switching losses decrease with the reduction in load current
and switching frequency. The approximate discontinuous mode operating frequency can be calculated as follows:
VOUT2 x L
F=
1 x 10-20 x RLoad x (RON)2
(1)
In continuous conduction mode, current flows continuously through the inductor and never ramps down to zero.
In this mode the operating frequency is greater than the discontinuous mode frequency and remains relatively
constant with load and line variations. The approximate continuous mode operating frequency can be calculated
as follows:
VOUT
F=
1.42 x 10-10 x RON
(2)
The output voltage (Vout) can be programmed by two external resistors as shown in Figure 2. The regulation
point can be calculated as follows:
VOUT = 2.5 x (R1 + R2) / R2
(3)
The feedback comparator in hysteretic regulators depend upon the output ripple voltage to switch the output
transistor on and off at regular intervals. In order for the internal comparator to respond quickly to changes in
output voltage, proportional to inductor current, a minimum amount of capacitor Equivalent Series Resistance
(ESR) is required. A ripple voltage of 25mV to 50mV is recommended at the feedback pin (FB) for stable
operation. In cases where the intrinsic capacitor ESR is too small, additional series resistance may be added.
For applications where lower output voltage ripple is required the load can be connected directly to the low ESR
output capacitor, as shown in Figure 2. The series resistor (R) will degrade the load regulation. Another
technique for enhancing the ripple voltage at the FB pin is to place a capacitor in parallel with the feedback
divider resistor R1. The addition of the capacitor reduces the attenuation of the ripple voltage from the feedback
divider

High Voltage Bias Regulator
The LM5007 contains an internal high voltage bias regulator. The input pin (Vin) can be connected directly to line
voltages from 9 V to 75 V. To avoid supply voltage transients due to long lead inductances on the input pin (Vin
Pin 8), it is always recommended to connect low ESR ceramic chip capacitor (≊ 0.1µF) between "Vin" pin and
"RTN" pin (pin 4), located close to LM5007. The regulator is internally current limited to 10mA. Upon power up,
the regulator is enabled and sources current into an external capacitor connected to the Vcc pin. When the
voltage on the Vcc pin reaches the regulation point of 7V, the controller output is enabled.
An external auxiliary supply voltage can be applied to the Vcc pin. If the auxiliary voltage is greater than 7 V, the
internal regulator will essentially shutoff, thus reducing internal power dissipation.

Over-Voltage Comparator
The over-voltage comparator is provided to protect the output from overvoltage conditions due to sudden input
line voltage changes or output loading changes. The over-voltage comparator monitors the FB pin versus an
internal 2.875V reference (OV_REF). If the voltage at FB rises above OV_REF the comparator immediately
terminates the buck switch on time pulse.
ON Time generator and Shutdown
The on time of the LM5007 is set inversely proportional to the input voltage by an external resistor connected
between Ron and Vin. The Ron terminal is a low impedance input biased at approximately 1.5V. Thus the
current through the resistor and into the Ron terminal is approximately proportional to Vin and used internally to
control the on timer. This scheme of input voltage feed-forward hysteretic operation achieves nearly constant
operational frequency over varying line and load conditions. The on time equation for the LM5007 is :
Ton = 1.42 x 10-10 x RON / VIN
(4)
The RON pin of the LM5007 also provides a shutdown function which disables the regulator and significantly
decreases quiescent power dissipation. By pulling the RON pin to below 0.7V logic threshold activates the low
power shutdown mode. The VIN quiescent current in the shutdown mode is approximately 100µA internal to the
LM5007 plus the current in the RON resistor.

Current Limit
The LM5007 contains an intelligent current limit off timer intended to reduce the foldback characteristic inherent
with fixed off-time over-current protection. If the current in the Buck switch exceeds 725mA the present cycle on
time is immediately terminated (cycle by cycle current limit). Following the termination of the cycle a nonresetable current limit off timer is initiated. The duration of the off time is a function of the external resistor (RCI)
and the FB pin voltage. When the FB pin voltage equals zero, the current limit off time is internally preset to
17uS. This condition occurs in short circuit operation when a maximum amount of off time is required.
In cases of overload (not complete short circuit) the current limit off time can be reduced as a function of the
output voltage (measured at the FB pin). Reducing the off time with smaller overloads reduces the amount of
foldback and also reduces the initial start-up time. The current limit off time for a given FB pin voltage and RCI
resistor can be calculated by the following equation:

Applications utilizing low resistance inductors and/or a low voltage drop rectifier may require special evaluation at
high line, short circuit conditions. In this special case the preset 17µs (FB = 0V) off time may be insufficient to
balance the inductor volt*time product. Additional inductor resistance, output resistance or a larger voltage drop
rectifier may be necessary to balance the inductor cycle volt*time product and limit the short circuit current.
N-Channel Buck Switch and Driver
The LM5007 integrates an N-Channel Buck switch and associated floating high voltage gate driver. This gate
driver circuit works in conjunction with an external bootstrap capacitor and an internal high voltage diode. The
bootstrap capacitor is charged by VCC through the internal high voltage diode. A 0.01uF ceramic capacitor
connected between the BST pin and SW pin is recommended.
During each cycle when the Buck switch turns off, the SW pin is approximately 0V. When the SW pin voltage is
low, the bootstrap capacitor will be charged from Vcc through the internal diode. The minimum off timer, set to
300ns, ensures that there will be a minimum interval every cycle to recharge the bootstrap capacitor.
An external re-circulating diode from the SW pin to ground is necessary to carry the inductor current after the
internal Buck switch turns off. This external diode must be of the Ultra-fast or Schottky type to reduce turn-on
losses and current over-shoot. The reverse voltage rating of the re-circulating diode must be greater than the
maximum line input voltage.
Thermal Protection
Internal Thermal Shutdown circuitry is provided to protect the integrated circuit in the event the maximum junction
temperature is exceeded. When thermal protection is activated, typically at 165 degrees Celsius, the controller is
forced into a low power reset state, disabling the output driver. This feature is provided to prevent catastrophic
failures from accidental device overheating.
Minimum Load Current
A minimum load current of 1 mA is required to maintain proper operation. If the load current falls below that level,
the bootstrap capacitor may discharge during the long off-time, and the circuit will either shutdown, or cycle on
and off at a low frequency. If the load current is expected to drop below 1 mA in the application, the feedback
resistors should be chosen low enough in value so they provide the minimum required current at nominal Vout.

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)

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.
