DESCRIPTION
NO.
Output voltage pin. The VOUT pin is connected to the internal output inductor. Connect the VOUT pin
to an external output capacitor and the output load. The output capacitor connections must be made
as close as possible to the VOUT and GND pin 11 of the module. See 节 10.2.
1
VOUT
O
Soft-start programming pin. If the SS pin is floating, the output voltage ramp up time is approximately
1 ms after the device is enabled by the EN pin. If a 100-kΩ resistor is placed from the SS pin to GND,
the internal soft start is disabled and the output voltage ramps up immediately after the device is
enabled with the EN pin. Other output voltage ramp up times can be obtained by connecting an
appropriate capacitance from the SS pin to GND.
2
SS
I
Ground pins. Connect all GND pins to the system ground plane. Pin 3 is not connected to GND
internal to the module. Connect pin 3 directly to pin 11 on the host PCB. See 节 10.2.

4, 5
GND
VIN
G
I
Input supply pins. The VIN pins are connected to the internal controller and power MOSFETs. Connect
the VIN pins to an external input capacitor and the input power source. The input capacitor
connections must be made as close as possible to the VIN pins and GND pin 6 of the module. See 节
10.2.
Enable hysteresis pin. The open-drain HYS pin can be used along with external resistors to program
the hysteresis of a user-defined UVLO using the EN pin. HYS is internally pulled to GND when EN is
below its turnon threshold and HYS goes open drain when EN is above its turnon threshold.
7
HYS
O
Output voltage feedback pin. For fixed output voltage options, the SENSE+ pin must be externally
connected to VOUT. For the adjustable output voltage option, the FB pin must be connected to an
external resistor divider that is connected between VOUT and GND.
8
9
SENSE+/FB
EN
I
I
Enable pin. The module is enabled when the EN pin is pulled high and disabled when the EN pin is
pulled low. An external resistor divider can be connected to the EN pin to act as an external UVLO.
Power Good pin. The open-drain PGOOD pin is pulled low when the SENSE+ or FB pin is below the
VOUT regulation target. An external 10-kΩ to 100-kΩ pullup resistor can be used to pull the PGOOD
pin high when VOUT meets the regulation target.

7 Detailed Description
7.1 Overview
The TPSM265R1 converter is an easy-to-use, synchronous buck, DC-DC power module that operates from a 3-
V to 65-V supply voltage. The device is intended for step-down conversions from 3.3-V, 5-V, 12-V, 24-V, and 48-
V unregulated, semi-regulated, or fully-regulated supply rails. With integrated power controller, inductor, and
MOSFETs, the TPSM265R1 delivers up to 100-mA DC load current, with high efficiency and ultra-low input
quiescent current, in a very small solution size. Although designed for simple implementation, this device offers
flexibility to optimize its usage according to the target application. Operation in pulse frequency modulation
(PFM) mode achieves exceptional light-load efficiency performance. Control-loop compensation is not required,
reducing design time and external component count.
The TPSM265R1 incorporates several features for comprehensive system requirements, including an open-
drain Power Good circuit for power-rail sequencing and fault reporting, internally-fixed, or externally-adjustable
soft start, monotonic start-up into prebiased loads, precision enable with customizable hysteresis for
programmable line undervoltage lockout (UVLO), and thermal shutdown with automatic recovery. These features
enable a flexible and easy-to-use platform for a wide range of applications. The pin arrangement is designed for
simple layout, requiring as few as two external components.

7.3 Feature Description
7.3.1 Adjustable Output Voltage (FB)
The TPSM265R1 has three voltage feedback options: fixed 3.3 V, fixed 5 V, and adjustable 1.223 V to 15 V. The
fixed 3.3-V and 5-V versions include internal feedback resistors that sense the output directly through the
SENSE+ pin; the adjustable voltage option senses the output through an external resistor divider connected
from the output to the FB pin.
Setting the output voltage of the adjustable option requires two resistors: RFBT and RFBB (see 图 7-1). Connect
RFBT between VOUT, at the regulation point, and the FB pin. Connect RFBB between the FB pin and GND (pin 6).
A resistor divider programs the ratio from output voltage VOUT to FB. The recommended value of RFBT is 100
kΩ. The value for RFBB can be calculated using 方程式 1.

(1) RFBT = 100 kΩ
Selecting an RFBT value of 100 kΩ is recommended for most applications. A larger RFBT consumes less DC
current, which is mandatory if light-load efficiency, is critical. However, RFBT larger than 1 MΩ is not
recommended as the feedback path becomes more susceptible to noise. High feedback resistance generally
requires more careful layout of the feedback path. It is important to keep the feedback trace as short as possible
while keeping the feedback trace away from the noisy area of the PCB. For more layout recommendations, see
节 10.

7.3.2 Input Capacitor Selection
The TPSM265R1 requires a minimum of 1 µF of ceramic type input capacitance. Use only high-quality ceramic
type X5R or X7R capacitors with sufficient voltage rating. TI recommends adding additional capacitance for
applications with transient load requirements. The voltage rating of input capacitors must be greater than the
maximum input voltage. To compensate for the derating of ceramic capacitors, TI recommends a voltage rating
of twice the maximum input voltage or placing multiple capacitors in parallel. 表 7-2 includes a preferred list of

7.3.4 Precision Enable (EN), Undervoltage Lockout (UVLO), and Hysteresis (HYS)
The EN pin provides precision ON and OFF control for the TPSM265R1. Once the EN pin voltage exceeds the
threshold voltage, the device starts operation. The simplest way to enable the TPSM265R1 is to connect EN
directly to VIN. This allows the TPSM265R1 to start up when VIN is within its valid operating range. An external
logic signal can also be used to drive the EN input to toggle the output on and off and for system sequencing or
protection.
The TPSM265R1 implements internal undervoltage lockout (UVLO) circuitry on the VIN pin. The device is
disabled when the VIN pin voltage is below the internal VIN UVLO threshold. The internal VIN UVLO rising
threshold is 2.95 V (max) with a typical hysteresis of 300 mV.
If an application requires a higher UVLO threshold, the EN input supports adjustable UVLO by connecting a
resistor divider from VIN to the EN pin. The EN pin connects to an internal comparator referenced to a 1.212-V
bandgap voltage with 68-mV hysteresis. However, applications requiring specific power-up and power-down
requirements can program the hysteresis voltage independently using the HYS pin. 图 7-2 shows the resistor
divider connection to establish a precision UVLO level with fixed internal hysteresis. 图 7-3 shows the resistor
divider connection used to set the precision UVLO level as well as the adjustable hysteresis.

There is also a low IQ shutdown mode when EN is pulled below 0.6 V (typ). If EN is below this shutdown
threshold, the internal LDO regulator powers off, shutting down the bias currents of the TPSM265R1. The
TPSM265R1 operates in standby mode when the EN voltage is between the shutdown and precision enable
thresholds.

7.3.5 PFM Operation
The TPSM265R1 operates in Pulse Frequency Modulation (PFM) mode. The TPSM265R1 behaves as a
hysteretic voltage regulator operating within upper and lower feedback regulation thresholds with typical 10 mV
of hysteresis. 图 7-4 is a representation of the relevant voltage waveforms and inductor current waveform. The
TPSM265R1 provides the required switching pulses to recharge the output capacitance, followed by a sleep
period where most of the internal circuits are shut off. The load current is supported by the output capacitor
during this time, and the TPSM265R1 current consumption approaches the sleep quiescent current of 10.5 μA
(typ). The sleep period duration depends on load current and output capacitance.

7.3.6 Power Good (PGOOD)
The TPSM265R1 provides a PGOOD signal to indicate when the output voltage is within regulation. Use the
PGOOD signal for output monitoring, fault protection, or start-up sequencing of downstream converters. PGOOD
is an open-drain output that requires a pullup resistor to a DC supply not greater than 12 V. Typical range of
pullup resistance is 10 kΩ to 100 kΩ. If necessary, use a resistor divider to decrease the voltage from a higher
voltage pullup rail.
When the output voltage exceeds 94% of the setpoint, the internal PGOOD switch turns off and PGOOD can be
pulled high by the external pullup. If the FB voltage falls below 87% of the setpoint, the internal PGOOD switch
turns on, and PGOOD is pulled low to indicate that the output voltage is out of regulation. The rising edge of
PGOOD has a built-in deglitch delay of 5 µs.
7.3.7 Configurable Soft Start (SS)
The TPSM265R1 has a flexible and easy-to-use soft-start control pin, SS. The soft-start feature prevents inrush
current when power is first applied. Soft start is achieved by slowly ramping up the target regulation voltage
when the device is powered up or enabled. Selectable and adjustable start-up timing options include minimum
delay (no soft start), 900-µs internally fixed soft start, and an externally programmable soft start.
Leaving the SS pin open enables the internal soft-start control ramp with a soft-start interval of 900 µs. The soft-
start time can be increased by connecting an external capacitor, CSS, from SS to GND. Applications with a large
amount of output capacitance or higher output voltage can benefit from increasing the soft-start time. Longer
soft-start time reduces the supply current needed to charge the output capacitors and supply any output loading.
An internal current source, ISS, of 10 µA charges CSS and generates a ramp to control the ramp rate of the
output voltage. Use 方程式 4 to calculate the CSS capacitance for a desired soft-start time, tSS
.

CSS is discharged by an internal FET when VOUT is shut down by EN, UVLO, or thermal shutdown.
It is desirable in some applications for the output voltage to reach its nominal setpoint in the shortest possible
time. Connecting a 100-kΩ resistor from SS to GND disables the soft-start circuit, and the TPSM265R1
operates in current limit during start-up to rapidly charge the output capacitance.
7.3.7.1 Prebiased Start-up
To prevent discharge of a prebiased output voltage, the TPSM265R1 is capable of start-up into prebiased output
conditions. When a prebiased voltage is present at start-up, the TPSM265R1 waits until the soft-start ramp
voltage is above the prebiased voltage before it begins switching and then follows the soft-start ramp to the
regulation setpoint.
7.3.8 Overcurrent Protection (OCP)
The TPSM265R1 is protected from overcurrent conditions using cycle-by-cycle current limiting of the peak
inductor current. The current is compared every switching cycle to the current limit threshold. During an
overcurrent condition, the output voltage decreases.
7.3.9 Thermal Shutdown
Thermal shutdown is an integrated self-protection used to limit junction temperature and prevent damage related
to overheating. Thermal shutdown turns off the device when the junction temperature exceeds 170°C (typ) to
prevent further power dissipation and temperature rise. Junction temperature decreases after shutdown, and the
TPSM265R1 restarts when the junction temperature falls to 160°C (typ).
7.4 Device Functional Modes
7.4.1 Shutdown Mode
The EN pin provides ON and OFF control for the TPSM265R1. When VEN is below approximately 0.6 V, the
device is in shutdown mode. Both the internal LDO and the switching regulator are off. The quiescent current in
shutdown mode drops to 4.6 µA at VIN = 12 V. The TPSM265R1 also employs internal bias rail undervoltage
protection. If the internal bias supply voltage is below its UV threshold, the regulator remains off.
7.4.2 Standby Mode
The internal bias rail LDO has a lower enable threshold than the regulator itself. When VEN is above 0.6 V and
below the precision enable threshold (1.212 V typically), the internal LDO is on and regulating. The precision
enable circuitry is turned on once the internal VCC is above its UV threshold. The switching action and voltage
regulation are not enabled until VEN rises above the precision enable threshold.
7.4.3 Active Mode
The TPSM265R1 is in active mode when VEN and the internal bias rail are above their relevant thresholds, FB
has fallen below the lower hysteresis level, and boundary conduction mode is recharging the output capacitor to
the upper hysteresis level. There is a 4-µs wake-up delay from sleep to active states.
7.4.4 Sleep Mode
The TPSM265R1 is in sleep mode when VEN and the internal bias rail are above the relevant threshold levels,
VFB has exceeded the upper hysteresis level, and the output capacitor is sourcing the load current. In sleep
mode, the TPSM265R1 operates with very low quiescent current.

8.2.2.2 Output Voltage Setpoint
The output voltage of the TPSM265R1 device is externally adjustable using a resistor divider. The recommended
value of RFBT is 100 kΩ. The value for RFBB can be selected from 表 7-1 or calculated using 方程式 5:
1.223
RFBB
=
× RFBT
1.223
VOUT
(5)
For the desired output voltage of 5 V, the formula yields a value of 32.38 kΩ. Choose the closest available
standard value of 32.4 kΩ for RFBB
.
8.2.2.3 Input Capacitors
The TPSM265R1 requires a minimum input capacitance of 1-µF ceramic type. High-quality ceramic type X5R or
X7R capacitors with sufficient voltage rating are recommended. The voltage rating of input capacitors must be
greater than the maximum input voltage.
For this design, a single, 1-µF, 50-V ceramic capacitor is selected.
8.2.2.4 Output Capacitor Selection
The TPSM265R1 requires a minimum of 10 µF of ceramic output capacitance for proper operation. Additional
output capacitance can be added to reduce ripple voltage or for applications with transient load requirements.
For this design example, a single 10-µF, 16-V, ceramic capacitor is used.
8.2.2.5 UVLO Programming
Applications requiring a higher UVLO threshold can benefit from applying a resistor divider on the EN pin. The
values for the resistors can be calculated using 方程式 6 and 方程式 7.

9 Power Supply Recommendations
The TPSM265R1 is designed to operate from an input voltage supply range between 3 V and 65 V. This input
supply must be able to provide the maximum input current and maintain a voltage above the set UVLO voltage.
Ensure that the resistance of the input supply rail is low enough that an input current transient does not cause a
high enough drop at the TPSM265R1 supply rail to cause a false UVLO fault triggering and system reset. If the
input supply is located more than a few inches from the TPSM265R1, additional bulk capacitance can be
required in addition to the ceramic input capacitance. A 4.7-μF electrolytic capacitor is a typical choice for this
function, whereby the capacitor ESR provides a level of damping against input filter resonances. A typical ESR
of 0.5 Ω provides enough damping for most input circuit configurations.

10 Layout
The performance of any switching power supply depends as much upon the layout of the PCB as the component
selection. Use the following guidelines to design a PCB with the best power conversion performance, optimal
thermal performance, and minimal generation of unwanted EMI.
10.1 Layout Guidelines
To achieve optimal electrical and thermal performance, an optimized PCB layout is required. 图 10-1 and 图 10-2
show a typical PCB layout. Some considerations for an optimized layout are:
• Use large copper areas for power planes (VIN, VOUT, and GND) to minimize conduction loss and thermal
stress.
• Connect all GND pins together using copper plane or thick copper traces.
• Place ceramic input and output capacitors close to the device pins to minimize high frequency noise.
• Locate additional output capacitors between the ceramic capacitor and the load.
• Place RFBT and RFBB as close as possible to their respective pins.
• Use multiple vias to connect the power planes to internal layers.

10.2.1 Theta JA versus PCB Area
The amount of PCB copper affects the thermal performance of the device. 图 10-3 shows the effects of copper
area on the junction-to-ambient thermal resistance (RθJA) of the TPSM265R1. The junction-to-ambient thermal
resistance is plotted for a 4-layer PCB with an area from 0.5 cm2 to 39 cm2.
To determine the required copper area for an application:
1. Determine the maximum power dissipation of the device in the application by referencing the power
dissipation graphs in 节 6.6 to 节 6.10.
2. Calculate the maximum θJA using 方程式 9 and the maximum ambient temperature of the application.
