AP63201WU-7 from Diodes Incorporated, in a TSOT-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 | FB | input | Feedback sensing terminal for the output voltage, connected to the output resistive divider and referenced to the internal 0.8V reference. |
| 2 | EN | input | Enable input that turns the regulator on when driven high and off when driven low, with a precision 1.18V threshold used to program UVLO; attach to VIN or leave open for automatic startup. |
| 3 | VIN | power_in | Power input that supplies the IC and the step-down converter switches, to be driven from a 3.8V to 32V source and bypassed to GND with a suitably large capacitor. |
| 4 | GND | power_in | Power ground. |
| 5 | SW | output | Power switching output node that supplies the output through the LC filter, with a capacitor required from SW to BST to power the high-side switch. |
| 6 | BST | power_in | High-side gate drive boost input that supplies the drive for the high-side N-channel MOSFET, with a 100nF capacitor recommended from SW to BST. |
