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. |
