SCT2220TVBR

SCT · DC-DC Converters · TSOT-23-6L

SCT2220TVBR 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 GND power_in Power ground return for the IC and the low-side power MOSFET. Must be soldered directly to the board ground plane for proper thermal and electrical performance.
2 SW power_out Power switching output - the junction of the high-side and low-side MOSFETs. Connect the external buck inductor from SW to the output, and a 0.1 µF (or greater) bootstrap capacitor from SW to BST.
3 VIN power_in Power supply input, 4.2 V to 17 V (18 V absolute max). Supplies both the IC and the high-side power switch; bypass to GND with a suitably large ceramic capacitor placed close to the pin.
4 FB input Buck converter feedback sensing input. Connect a resistor divider from VOUT to FB to set the output voltage; the internal reference regulates FB to 0.8 V typical (0.78-0.82 V).
5 EN input Enable/UVLO logic input. Precision thresholds 1.18 V rising / 1.10 V falling with ~6.8 µA hysteresis current allow programmable UVLO via a resistor divider from VIN. Floating the pin enables the device; tie to GND (or below the low threshold) to shut down.
6 BST passive Bootstrap supply for the high-side MOSFET gate driver. Connect a 0.1 µF (or greater) ceramic capacitor between BST and SW to develop the boosted drive rail.

CAD (KiCad official)

  • Symbol: SCT2220TVBR
  • Footprint: Package_TO_SOT_SMD:SOT-23-6
  • 3D model: TSOT-23-6L (KiCad packages3D, STEP)
  • 3D model files: sct2220tvbr-etched.step / sct2220tvbr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sct2220tvbr.step / sct2220tvbr.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: SCT datasheet (17 pp, sha256 c9a21075d50243c2, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
