TD8113X

Shenzhen JingYang · DC-DC Converters · SOT-23-6

TD8113X from Shenzhen JingYang, in a SOT-23-6. 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 BOOT input High-side gate drive boost input; connect a 0.1µF or greater capacitor from SW to BOOT to power the high-side switch.
2 GND power_in Ground; the datasheet recommends connecting GND to a large copper area for thermal performance.
3 FB input Feedback input that senses the output voltage through a resistive divider; the feedback threshold is 0.6V and the output is adjustable from 0.6V to 15V.
4 EN input Enable input: drive high to turn the regulator on and low to turn it off, with a 100kΩ pull-up for automatic startup.
5 IN power_in Power input supplying the IC and the step-down switches; drive with a 4.5V to 18V source and bypass to GND with a suitably large capacitor.
6 SW power_out Power switching output that connects the output LC filter to the load; a boost capacitor is required from SW to BOOT.
