# SCT2330TVBR

**SCT** · DC-DC Converters · TSOT-23-6L

SCT2330TVBR from SCT, in a TSOT-23-6L. 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 | FB | input | Buck converter output feedback sensing voltage. Connect a resistor divider from VOUT to FB to set the output voltage. The device regulates FB to the internal 0.8V (typ) reference (0.792V-0.808V). |
| 2 | EN | input | Enable logic input. Floating the pin enables the device. Supports high-voltage input up to VIN, so it can be tied directly to VIN for automatic enable. Precision enable thresholds 1.18V rising / 1.1V falling allow programmable UVLO threshold and hysteresis. |
| 3 | VIN | power_in | Power supply input, 3.8V to 32V operating range (40V absolute max). Must be locally bypassed with a ceramic capacitor close to the pin. |
| 4 | GND | power_in | Power ground. Must be soldered directly to the ground plane for proper thermal dissipation and low-impedance return path. |
| 5 | SW | output | Switching node of the buck converter. Connect the output inductor between SW and VOUT. Also forms the low reference for the BST bootstrap capacitor. |
| 6 | BST | power_in | Bootstrap supply for the high-side power MOSFET gate driver. Connect a 0.1µF or greater ceramic capacitor between BST and SW. Absolute max 40V referenced to GND. |

## CAD (KiCad official)

- Symbol: `SCT2330TVBR`
- Footprint: `Package_TO_SOT_SMD:SOT-23-6`
- 3D model: TSOT-23-6L (KiCad packages3D, STEP)
- 3D model files: `sct2330tvbr-etched.step` / `sct2330tvbr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `sct2330tvbr.step` / `sct2330tvbr.glb` are the bare package body.
