TD6810

Techcode Semicon · DC-DC Converters · SOT-23-5

TD6810 from Techcode Semicon, in a SOT-23-5. 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 RUN input Run Control Input. Forcing this pin above 1.5V enables the part; forcing it below 0.3V shuts the device down. In shutdown all functions are disabled, drawing <1uA supply current. Do not leave RUN floating.
2 GND power_in Ground pin. Serves as the reference for VIN decoupling; connect the VIN 2.2uF (or greater) ceramic capacitor closely between VIN and this pin.
3 SW output Switch Node Connection to inductor. This pin connects to the drains of the internal main P-channel and synchronous N-channel power MOSFET switches. Absolute maximum SW voltage is -0.3V to (VIN+0.3V); peak SW current up to 1.3A.
4 VIN power_in Main Supply Pin (2.5V-5.5V operating, 6V absolute max). Must be closely decoupled to GND (pin 2) with a 2.2uF or greater ceramic capacitor.
5 VFB/VOUT input Feedback / Output Voltage sense pin. On the adjustable version this is VFB, receiving the feedback voltage from an external resistive divider across the output (regulated to 0.6V typ.). On the fixed-output versions (TD6810-1.2/1.5/1.8) this pin is tied directly to VOUT; an internal resistive divider scales the output down for comparison to the 0.6V internal reference.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
td6810.step 85 KB You want the bare part, or you mark your own boards.
td6810-etched.step 1.4 MB You want the part with TD6810 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 343 faces against 102 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

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