GR1938EKBG

Grenergy(南京绿芯) · IC · SOP-8

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.
