CBM2576HVS-12

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

CBM2576HVS-12 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 Supply input that feeds the internal regulator and the switch, with an operating supply voltage of 60 V and an absolute maximum of 63 V.
2 OUTPUT output Emitter of the internal 3 A switching transistor that drives the external inductor, with cycle-by-cycle current limit of 4.2 A min to 6.9 A max at 25 C.
3 GND power_in Ground reference for the regulator and its internal circuitry.
4 FB input Feedback input to the error amplifier through the internal divider (R2 = 10.56k, R1 = 1.2k for the 12 V version) that regulates the output to 12 V.
5 ON/OFF input Active-low shutdown input where below 0.8 V to 1.0 V max switches the regulator on and above 2.2 V to 2.4 V min puts it in standby, with an absolute maximum range of -0.3 V to +25 V.
6 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
