FP6722S6 from Fitipower Integrated Tech, 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 node pin connected to the inductor. |
| 2 | GND | power_in | Ground pin. |
| 3 | EN | input | Chip-enable input; the converter works when high and shuts off when low (VIL max 0.4V, VIH min 1.2V for 1.5V<VIN<5V). |
| 4 | FB | input | Feedback input connected to a resistor divider to set output voltage from 1.8V to 5.5V; feedback voltage is typically 0.5V. |
| 5 | VOUT | power_out | Output voltage pin, adjustable from 1.8V to 5.5V. |
| 6 | VIN | power_in | Input voltage pin, operating range 0.75V to VOUT. |
