**GR** · LED Drivers · SOT-23

GR6202 from GR, in a SOT-23. 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 | LX | output | Power transistor output (switch node) that drives the external inductor; the datasheet gives no voltage or current limit for this pin. |
| 2 | GND | power_in | Chip ground pin (SOT23-3 standard pinout). |
| 3 | VDD | power_in | Power supply input; the absolute maximum input voltage is 5.0 V and the stated operating voltage range is 1.8 V to 3.2 V. |

## CAD (KiCad official)

- Symbol: `GR6202`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `gr6202-etched.step` / `gr6202-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `gr6202.step` / `gr6202.glb` are the bare package body.
