Capable of driving a 0.5A load over a 9V-42V input
voltage range, this device is easy to apply and is
provided in the small VSSOP-8 and the thermally
enhanced WSON-8 packages. Ultra-fast transient
response is achieved through the use of a constant
on-time architecture with Vin feed forward. This
feature provides an almost constant operating
frequency over load and input voltage variations. The
operating frequency can be adjusted with a single
resistor. This architecture is easy to use and tolerant
of component selection. An intelligent current limit is
implemented in the LM25007 with forced off time that
is inversely proportional to Vout thus ensuring
recovery from fault conditions. The output voltage
may be set from 2.5V to >30V. To improve efficiency
in light load applications, the Vcc pin can be
connected to an external voltage source to eliminate
the drop through the internal regulator. Additional

DETAILED OPERATING DESCRIPTION
The LM25007 is a monolithic step-down switching regulator featuring all of the functions needed to implement
low cost, efficient, power supply. Capable of driving a 0.5Amp load over a 9-42V input voltage range, this device
is easy to apply and is provided in the small VSSOP-8 and the thermally enhanced WSON-8 packages. Ultra-fast
transient response is achieved through the use of a constant on-time architecture with Vin feed forward. This
feature provides and almost constant operating frequency over load and input voltage variations. The operating
frequency may be adjusted up to 800kHz depending on input and output voltages. This architecture is easy to
use and tolerant of component selection. An intelligent current limit is implemented in the LM25007 with forced
off time that is inversely proportional to Vout to ensure recovery from fault conditions. The output voltage may be
set from 2.5V to >30V. To improve efficiency in light load applications, the Vcc pin can be tied to an external
voltage source thus eliminating the drop through the integrated internal regulator. Additional protection features
include: thermal shutdown, Vcc under-voltage lockout, gate drive under-voltage lockout, and max duty cycle
limiter.
Hysteretic Control Circuit Overview
The LM25007 is a Buck DC-DC regulator that uses a constant 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 LM25007 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 LM25007 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 is 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 6. The regulated
voltage is calculated as follows:
VOUT = 2.5 x (R3 + R4) / R4
(3)
The feedback comparator in hysteretic regulators depends on 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 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 6. The series resistor (R5) 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 R3. The addition of the capacitor reduces the attenuation of the ripple voltage from the feedback
divider.
High Voltage Bias Regulator (VCC)
The LM25007 contains an internal high voltage bias regulator. The input pin (Vin) can be connected directly to
line voltages from 9 to 42 Volts. To avoid supply voltage transients due to long lead inductances on the input pin
(VIN), it is always recommended to connect a low ESR ceramic chip capacitor (≊ 0.1µF) between VIN and RTN
pins located close to the LM25007. The regulator is internally current limited to 11mA. 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 its UVLO level (6.3V), the controller output is enabled.
An external auxiliary supply voltage can be diode connected to the Vcc pin. If the auxiliary voltage is greater than
7 Volts the internal regulator will shutoff, thus reducing internal power dissipation. Do not exceed 14V at VCC.

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. If the voltage at FB rises above 2.875V the comparator immediately terminates the
buck switch on-time pulse.
ON Time generator and Shutdown
The on-time of the LM25007 is set inversely proportional to the input voltage by an external resistor connected
between RON/SD and VIN. The RON/SD terminal is a low impedance input biased at approximately 1.5V. The
current through the resistor and into the RON/SD pin 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 LM25007 is :
Ton = 1.42 x 10-10 x RON / VIN
(4)
The RON/SD pin of the LM25007 also provides a shutdown function which disables the regulator and
significantly decreases quiescent power dissipation. By pulling the pin below 0.7V activates the low power
shutdown mode. The VIN quiescent current in the shutdown mode is approximately 100µA internal to the
LM25007 plus the current in the RON resistor. See Figure 8.

Current Limit
The LM25007 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 non-
resetable current limit off timer is initiated. The duration of the off time is a function of the external resistor (RCL)
and the FB pin voltage. When the FB pin voltage equals zero, the current limit off-time is internally preset to
17µs. 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 is 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 RCL resistor can
be calculated by the following equation:
Toff = 10-5 / (0.59 + (VFB / 7.22 x 10-6 x RCL))
(5)
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 LM25007 integrates an N-Channel Buck switch and associated floating high voltage gate driver. The 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 is 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 circuitwill 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.

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
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.

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.
