TPS54386TPWPRQ1

Texas Instruments · DC-DC Converters · HTSSOP-14-EP

TPS54386TPWPRQ1 from Texas Instruments, in a HTSSOP-14-EP. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 PVDD1 power_in Power input to output 1 high-side MOSFET; bypass to ground with 10-μF or greater low-ESR ceramic capacitor.
2 BOOT1 input Bootstrap supply for output 1 high-side gate driver; connect 22-nF to 82-nF capacitor between this pin and SW1.
3 SW1 output Switching output for output 1 PWM; snubber recommended to reduce ringing on this node.
4 GND power_in Ground reference pin for device; connect directly to thermal pad on bottom side.
5 EN1 input Active-low enable input for output 1; enables when <0.9 V, disables when >1.55 V with 50-mV hysteresis.
6 EN2 input Active-low enable input for output 2; enables when <0.9 V, disables when >1.55 V with 50-mV hysteresis.
7 FB1 input Voltage feedback input for output 1; error amplifier regulates this pin to 800-mV internal reference voltage.
8 FB2 input Voltage feedback input for output 2; error amplifier regulates this pin to 800-mV internal reference voltage.
9 ILIM2 input Current limit threshold selection input for output 2; internal 150-kΩ divider connects BP to this pin and to ground.
10 SEQ input Sequencing mode selection pin; internal 150-kΩ divider connects BP to this pin and to ground for output startup sequence control.
11 BP power_out Regulated 5.25-V output from internal LDO regulator; bypass to ground with 4.7-μF to 10-μF low-ESR ceramic capacitor.
12 SW2 output Switching output for output 2 PWM; snubber recommended to reduce ringing on this node.
13 BOOT2 input Bootstrap supply for output 2 high-side gate driver; connect 22-nF to 82-nF capacitor between this pin and SW2.
14 PVDD2 power_in Power input for device control circuitry and output 2 high-side MOSFET; bypass to ground with 10-μF or greater low-ESR ceramic capacitor.
15 Thermal pad passive Exposed pad (from the footprint; not named in the datasheet pin table).
