TX4204

XDS · DC-DC Converters · SOT-23-3

TX4204 from XDS, in a SOT-23-3. 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 Ground reference for the device. Connect to system ground.
2 SW power_out Switching node. Connect to the boost inductor (typ. 22uH) between VIN and this pin. Internal power switch drives this node; max SW current 0.3A.
3 VOUT power_out Regulated boost output voltage (nominal 3.3V, ±2.5%). Connect to output filter capacitor (typ. 100uF). Absolute maximum 5V.

CAD (KiCad official)

  • Symbol: TX4204
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3 (KiCad packages3D, STEP)
  • 3D model files: tx4204-etched.step / tx4204-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tx4204.step / tx4204.glb are the bare package body.

Provenance

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

  • Datasheet: XDS datasheet (9 pp, sha256 8f1d2a99970205c3, retrieved 2026-08-17, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • 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).
