**Grenergy(南京绿芯)** · DC-DC Converters · SOT23-6

GR8386CG from Grenergy(南京绿芯), in a SOT23-6. 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 | VIN | power_in | High-voltage linear regulator input, rated -1V to 130V to GND as an absolute maximum. |
| 2 | GND | power_in | Ground reference for the controller. |
| 3 | NC | unconnected | No internal connection; leave unconnected. |
| 4 | VDD | power_out | Internal regulator output that supplies the IC; recommended 4V to 6V to GND with a 0.1 µF to 1 µF capacitor, and absolute maximum -0.3V to 7V. |
| 5 | GATE | output | Gate drive output for the synchronous rectifier MOSFET, with absolute maximum -0.3V to 7V, peak source current 0.8A and peak sink current 1.3A at CLoad = 10nF (guaranteed by design). |
| 6 | VD | input | MOSFET drain voltage sense input, recommended -0.3V to 120V to GND; turn-on threshold is -100mV and gate turns off near 0mV. |
