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). |
