FP6396S5 from Fitipower Integrated Tech, in a SOT-23-5. 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 | EN | input | Enable control pin: pull high to turn the IC on and low to disable it, must not be left floating (VEN high min 1.5V, low max 0.4V). |
| 2 | GND | power_in | Ground pin. |
| 3 | LX | passive | Power switching node to which the external inductor is connected, rated -0.3V to (VIN+0.3V). |
| 4 | VIN | power_in | Power supply input pin for 2.5V to 6V operation (6.5V absolute max), with input capacitors placed as close as possible between VIN and GND. |
| 5 | FB | input | Voltage feedback input connected to VOUT through a resistive divider, regulated at 0.6V. |
