# AP5727WG-7

**Diodes Incorporated** · LCD Drivers · SOT-25

AP5727WG-7 from Diodes Incorporated, in a SOT-25. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SW | output | Switch Pin for inductor/diode connection; minimize trace area to reduce EMI. |
| 2 | GND | power_in | Ground pin. |
| 3 | FB | input | Feedback Pin with 1.25 V reference voltage. |
| 4 | EN | input | On/Off control input; high enables converter, low disables; cannot be left floating. |
| 5 | VIN | power_in | Input Supply Pin. Must be locally decoupled with 4.7 μF recommended to reduce input noise. |
