OC6813T33 from OCX, in a SOT23-3. 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 pin for the device; it is the return reference for the boost converter. |
| 2 | LX | output | Switch pin that connects to the external inductor; the datasheet's absolute maximum voltage for LX is 5 V. |
| 3 | VOUT | power_out | Boost output pin that delivers the regulated output (3.3 V for the OC6813T33); the absolute maximum voltage for VOUT is 5 V. |
