TD1601SADJ

Techcode Semicon · DC-DC Converters · TO-263-5

TD1601SADJ from Techcode Semicon, in a TO-263-5. 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 Vin power_in Input supply voltage, operating range 9V to 60V (absolute maximum -0.3 to 63V).
2 Output output Switching output, limited to -0.3V to Vin+0.3V absolute maximum.
3 GND power_in Ground.
4 FB input Output voltage feedback, regulated to 1.23V typical (1.200 to 1.26V) and limited to -0.3V to 5V absolute maximum.
5 ON/OFF input ON/OFF shutdown input, active when low or floating (regulator ON threshold 0.8V typical), limited to -0.3V to 5V absolute maximum.
6 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).

CAD (KiCad official)

  • Symbol: TD1601SADJ
  • Footprint: Package_TO_SOT_SMD:TO-263-5_TabPin6
  • 3D model: TO-263-5 (KiCad packages3D, STEP)
  • 3D model files: td1601sadj-etched.step / td1601sadj-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); td1601sadj.step / td1601sadj.glb are the bare package body.
