AP62201WU-7
Diodes Incorporated · DC-DC Converters · TSOT-23-6
AP62201WU-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 | GND | power_in | Power ground for the regulator, to which the input and output capacitors return and which should be connected to the GND plane with many vias for heat dissipation. |
| 2 | SW | power_out | Power switching output that is the switching node supplying power to the output, with the output LC filter connected from SW to the load. |
| 3 | VIN | power_in | Power input that supplies the IC and the step-down power MOSFETs and must be driven from a 4.2V to 18V source and bypassed to GND with a suitably large capacitor. |
| 4 | FB | input | Feedback sensing terminal for the output voltage, connected to the output resistive divider, with the regulation reference at 0.8V for AP62201. |
| 5 | EN | input | Enable input that turns the regulator on when driven above its 1.2V precision threshold and off when driven low, and can be left floating for automatic startup while also setting the UVLO thresholds. |
| 6 | BST | input | High-side gate drive boost input that supplies the high-side N-channel MOSFET driver, with a 100nF capacitor recommended from BST to SW. |
