TD1469

Techcode Semicon · DC-DC Converters · SOT-23-6

TD1469 from Techcode Semicon, in a SOT-23-6. 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 BS passive High-side gate drive bootstrap input. Supplies the drive voltage for the internal high-side N-channel MOSFET. Connect at least a 10nF capacitor from SW to BS (typical 10nF-100nF).
2 GND power_in Signal and power ground. Return for the internal control circuitry and low-side MOSFET source.
3 FB input Output feedback input. Senses the divided output voltage and regulates it to the internal 0.8V reference (VFB typ 0.812V). Connect a resistor divider from VOUT to set output between 0.8V and 90%VIN.
4 EN input Enable input. Digital logic input that turns the regulator on/off. Threshold is 1.1V rising with 200mV hysteresis. Pull up with a 1MΩ resistor for automatic startup; can be RC-delayed for sequencing.
5 VIN power_in Power supply input, 7V to 40V (abs max 43V). Feeds control circuitry, gate drivers, and the step-down power switches. Bypass with a ceramic capacitor and a suitably large bulk capacitor to GND.
6 SW power_out Power switching output. Drain of the internal N-channel high-side MOSFET / source of the low-side MOSFET. Connects to the external inductor of the output LC filter and to the bootstrap capacitor bottom plate.

CAD (KiCad official)

  • Symbol: TD1469
  • Footprint: Package_TO_SOT_SMD:SOT-23-6
  • 3D model: SOT-23-6 (KiCad packages3D, STEP)
  • 3D model files: td1469-etched.step / td1469-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); td1469.step / td1469.glb are the bare package body.

Provenance

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

  • Datasheet: Techcode Semicon datasheet (9 pp, sha256 b0c259ba557fdc65, 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).
