GR8874KG from Grenergy, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | RT | input | External resistor connection to ground for programming the switching frequency; frequency determined by fosc = 6500(KHz)/R(Kohm) with recommended operating range of 50 kHz to 130 kHz. |
| 2 | COMP | input | Voltage feedback input pin connected to external photo-coupler for duty cycle control; requires 1 nF to 10 nF bypass capacitor to ground for stability. |
| 3 | CS | input | Current sense input pin for cycle-by-cycle peak current limiting with maximum input voltage of 0.85V and 350ns leading-edge blanking time to filter switching transients. |
| 4 | GND | power_in | Ground reference pin for IC return and external circuit common. |
| 5 | OUT | output | Gate driver output for external MOSFET with 500 mA driving capability and internal Zener clamp at 13.5V for over-voltage protection. |
| 6 | VCC | power_in | Chip power supply input requiring 11.5V to 25V operating range; UVLO (under-voltage lockout) trip threshold at 15V (on) and 9.3V (off); over-voltage protection at 28V. |
| 7 | NC | unconnected | No connection; pin left floating or unconnected per design. |
| 8 | HV | power_in | High-voltage startup supply pin (0V to 500V) with integrated 1 mA current source enabling startup without external startup resistor; automatically disconnects via UVLO to minimize quiescent current. |
