GR1938EKBG from Grenergy(南京绿芯), in a SOP-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 | GND | power_in | Ground. |
| 2 | VCC | power_in | Power supply input; operating range Vcc=9~36V per the features list, absolute maximum 30V. |
| 3 | COMP | input | Voltage feedback pin, connected to an optocoupler to control the duty cycle; absolute maximum -0.3 to 7V. |
| 4 | CS | input | Current sense pin used to sense the MOSFET current; absolute maximum -0.3 to 7V. |
| 5 | DRAIN | passive | Drain of the internal 650V high-voltage MOSFET (pins 5-8 are tied together); drain voltage -0.3V to 650V. |
| 6 | DRAIN | passive | Drain of the internal 650V high-voltage MOSFET (pins 5-8 are tied together); drain voltage -0.3V to 650V. |
| 7 | DRAIN | passive | Drain of the internal 650V high-voltage MOSFET (pins 5-8 are tied together); drain voltage -0.3V to 650V. |
| 8 | DRAIN | passive | Drain of the internal 650V high-voltage MOSFET (pins 5-8 are tied together); drain voltage -0.3V to 650V. |
