TD1410P

Techcode Semicon · DC-DC Converters · SOIC-8

TD1410P from Techcode Semicon, in a SOIC-8. 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 NC unconnected Not connected. Leave floating or tie to a stable DC node per layout best practice.
2 VIN power_in Supply voltage input pin. TD1410 operates from a 3.6 V to 20 V DC input (absolute max 20 V). Bypass VIN to GND with a suitably large low-ESR capacitor (>10 µF) to eliminate switching noise and supply the discontinuous switching current.
3 SW output Power switch output pin (internal PMOS drain). Voltage swings between (VIN - VSAT) and approximately -0.5 V with a duty cycle of about VOUT/VIN. Connect to the external inductor and Schottky catch diode; keep PCB copper area minimal to reduce EMI coupling.
4 GND power_in Ground pin. Should be routed outside the Schottky-diode-to-output-capacitor ground path to prevent switching current spikes from inducing voltage noise into the IC. Use a ground plane to connect input cap, output cap, and this pin.
5 FB input Feedback pin. Senses the output voltage through an external resistor divider and regulates it to the internal 1.222 V reference (VFB typ 1.222 V, 1.185-1.26 V). Feedback bias current is 0.1 µA typ (0.5 µA max). Keep FB trace away from the SW node.
6 NC unconnected Not connected. Leave floating or tie to a stable DC node per layout best practice.
7 EN input Enable pin. Digital input that turns the regulator on/off; drive high to enable, low to shut down (shutdown supply current ~30 µA). Threshold typ 1.2 V (0.7 V min, 1.7 V max). Absolute maximum EN voltage is 12 V. For automatic startup, a resistive divider from VIN to GND may be used.
8 NC unconnected Not connected. Leave floating or tie to a stable DC node per layout best practice.
