AP5725WG-7 from Diodes Incorporated, in a SOT-26. 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 pin for the inductor/diode connection; minimize trace area here to reduce EMI (rated -0.3 to 34 V). |
| 2 | GND | power_in | Ground pin. |
| 3 | FB | input | Feedback pin with 0.25V reference; connect the cathode of the lowest LED and the sense resistor RSET = 0.25V / ILED. |
| 4 | EN | input | Converter on/off control input (high ≥1.5V on, low ≤0.4V off); connect to input source for automatic startup and do not leave floating. |
| 5 | OVP | input | Output voltage detect pin for over voltage protection, with threshold of 26 to 34 V (30 V typ). |
| 6 | VIN | power_in | Input supply pin (2.7 to 5.5 V operating) that must be locally bypassed with 1μF or 2.2μF to reduce input noise. |
