CBM2576HVS-ADJ

Corebai Microelectronics · DC-DC Converters · TO-263-5

CBM2576HVS-ADJ from Corebai Microelectronics, in a TO-263-5. 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 VIN power_in Unregulated supply input for the regulator and internal circuitry, operating range up to 60V (absolute maximum 63V).
2 OUTPUT output Emitter of the internal 3A switching transistor that drives the external inductor and catch diode, with 4.2A to 6.9A current limit at 25°C.
3 GND power_in Ground reference for the regulator.
4 FB input Feedback input that senses the output voltage through an external divider and regulates to a 1.23V reference (1.217V to 1.243V at 25°C) in the adjustable version.
5 ON/OFF input Active-low TTL shutdown input: below 1.0V (max) at 25°C switches the regulator on, above 2.2V (min) switches it off into low-power standby, with an absolute maximum of +25V.
6 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
