# 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. |
