APW7137BI-TRG

Anpec Elec · DC-DC Converters · SOT-23-5

APW7137BI-TRG from Anpec Elec, in a SOT-23-5. 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 LX output Switch pin that connects to the inductor and the external Schottky diode; the datasheet rates LX-to-GND at -0.3 to 40 V (absolute maximum) and -0.3 to 36 V (recommended).
2 GND power_in Power and signal ground pin.
3 FB input Feedback input that regulates the output at 1.23 V through an external resistor divider, which sets VOUT from VIN up to 30 V.
4 EN input Enable input: forcing above 1.0 V enables the device and forcing below 0.4 V shuts it down to under 1 µA supply current; it must not be left floating.
5 VIN power_in Main supply pin, operating from 2.5 V to 6 V, that must be closely decoupled to GND with a 2.2 µF or greater ceramic capacitor.
