TPS54331GDR

Texas Instruments · DC-DC Converters · SOIC-8

TPS54331GDR from Texas Instruments, in a SOIC-8. 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 BOOT output A 0.1μF bootstrap capacitor is required between the BOOT and PH pins, and if the voltage on this capacitor falls below the minimum requirement, the high-side MOSFET is forced off until the capacitor is refreshed.
2 VIN power_in This pin is the 3.5V to 28V input supply voltage pin.
3 EN input This enable pin must be pulled below 1.25V to disable the device, can be left floating to enable it, and two resistors are recommended to program the input UVLO.
4 SS input This slow-start pin sets the output rise time through the external capacitor connected from it to ground.
5 VSENSE input This pin is the inverting node of the transconductance (gm) error amplifier.
6 COMP output This pin is the error amplifier output and PWM comparator input, and the frequency compensation components are connected to it.
7 GND power_in This is the ground pin.
8 PH output The PH pin is the source of the internal high-side power MOSFET and forms the switch node with the catch diode and output inductor.
