GR1230RCG

Grenergy · AC-DC Controllers & Regulators · SOT-26

GR1230RCG from Grenergy, in a SOT-26. 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 GND power_in Ground reference pin for the controller.
2 COMP input Voltage feedback pin. A photo-coupler is connected here to control the duty cycle. Open-loop voltage ~5.2V; OLP trip level ~4.35V; requires a paralleling capacitor of 1-33 nF for noise filtering.
3 QRD input Quasi-resonant detection and OVP input. Upper clamp ~4.6V (IZCD=0.5mA), lower clamp ~-0.3V (IZCD=0.3mA); OVP threshold ~3.5V, UVP threshold ~0.5V.
4 CS input Current sense pin, connected to the external sense resistor for sensing the primary MOSFET current signal. Vcsmax(ON Time>4us) ~0.85V; internal slope compensation ~0.3V; leading-edge blanking ~350 ns.
5 VCC power_in Power supply pin. Recommended supply 9.5-26.5V; UVLO-ON ~16V, UVLO-OFF ~7.5V; internal VCC OVP ~28V. Requires a 2.2-10 µF bulk capacitor plus a small (0.1-0.47 µF) SMD ceramic capacitor close to the pin.
6 OUT output Gate driver output for the external primary MOSFET. Output low ≤1V @ 20mA; internal VGATE clamp ~13.5V (VCC=17V); typical rise/fall time 330/45 ns into 1nF load.
