BL8536CB3TR36

BL Shanghai Belling · DC-DC Converters · SOT-23

BL8536CB3TR36 from BL Shanghai Belling, in a SOT-23. 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 GND power_in Ground reference for the converter. Return path for input and output ceramic capacitors; keep trace as short as possible to the output cap ground.
2 SW power_out Switching node. Connects the internal synchronous power stage to the external boost inductor (typ. 2.2uH-4.7uH) which ties back to VIN. Absolute maximum -0.3V to 6V.
3 OUT power_out Regulated boost output voltage pin (3.6V for CB3TR36 variant, factory-set range 1.8V-3.6V). Also supplies the IC's internal bias once started. Requires a 10uF low-ESR ceramic capacitor closely connected to GND; absolute maximum -0.3V to 6V.
