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. |
