AP5725WG-7

Diodes Incorporated · LED Drivers · SOT-26

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.
