TPFP6291LR-G1

TECH PUBLIC · DC-DC Converters · SOT-23-6

TPFP6291LR-G1 from TECH PUBLIC, in a SOT-23-6. 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 SW passive Switch pin connected to the internal power MOSFET (2.5A switch current), with absolute maximum VSW of -0.3 to 18V.
2 GND power_in Ground pin.
3 FB input Voltage feedback pin with 0.6V reference (0.588 to 0.612V), set by an external resistor divider.
4 EN input Enable pin; logic high is 1.0V minimum and logic low is 0.6V maximum.
5 VIN power_in Input supply pin, operating range 2.6V to 6V.
6 ISET passive Output overcurrent threshold set by an external resistor to GND, where IISET=48000/RISET.
