BL8531CC3TR30

BL(Shanghai Belling) · DC-DC Converters · SOT-89-3

BL8531CC3TR30 from BL(Shanghai Belling), in a SOT-89-3. 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 Ground pin of the controller.
2 OUT power_in Output pin that supplies power to the internal circuitry, with an absolute maximum voltage range of -0.3V to 12V.
3 EXT output Switching pin that drives the external NMOSFET or NPN transistor, with an absolute maximum voltage of -0.3V to (VOUT+0.3V).
