SGM61232XPS8G from SGMICRO, in a SOIC-8. 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 | BOOT | output | Bootstrap input for the N-MOSFET gate driver supply; connect to SW with a 0.1μF ceramic capacitor, and the MOSFET turns off if the BOOT capacitor voltage drops below the BOOT-UVLO level. |
| 2 | VIN | power_in | Input supply voltage; connect to a 4V to 28V power source. |
| 3 | EN | input | Active-high enable input that floats or pulls up to enable and is pulled below 1.08V to disable the device, with VIN UVLO programmable through a resistor divider from VIN. |
| 4 | SS | input | Soft-start input where an external capacitor on SS programs the output rise time during startup. |
| 5 | VSENSE | input | Transconductance error amplifier inverting input used as the feedback input to sense and regulate VOUT, with output voltage set by a resistor divider from the output. |
| 6 | COMP | output | Error amplifier output, internally connected to the PWM comparator input, with the compensation network placed between COMP and GND. |
| 7 | GND | power_in | Ground pin. |
| 8 | SW | power_out | Switching node and source of the internal MOSFET, connected to the catch diode cathode, the bootstrap capacitor and the inductor. |
