CBM2576HVS-5.0

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

CBM2576HVS-5.0 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 of the regulator, operating range up to 60 V (absolute maximum 63 V).
2 OUTPUT output Emitter of the internal 3 A switching transistor that drives the external inductor, with cycle-by-cycle current limit (4.2 A min to 6.9 A max at 25C).
3 GND power_in Ground pin of the regulator.
4 FB input Feedback input to the error amplifier, sensing the output voltage; the adjustable version regulates this pin to 1.23 V reference.
5 ON/OFF input Active-low TTL-level shutdown input; below 1.0 V (25C) the switch is on, above 2.2 V it is off in standby, with an absolute maximum of -0.3 V to +25 V.
6 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
