**OCX** · DC-DC Converters · SOT23-3

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. |

## CAD (KiCad official)

- Symbol: `OC6813T33`
- Footprint: `Package_TO_SOT_SMD:SOT-23-3`
- 3D model: SOT23-3 (KiCad packages3D, STEP)
- 3D model files: `oc6813t33-etched.step` / `oc6813t33-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `oc6813t33.step` / `oc6813t33.glb` are the bare package body.
