# TD8102X

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

TD8102X 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 | GND | power_in | Ground. |
| 2 | LX | output | Switching pin; the absolute maximum LX voltage is -0.3 V to 19 V. |
| 3 | IN | power_in | Power supply pin; the operating input range is 4.5 V to 18 V and the absolute maximum is 19 V. |
| 4 | FB | input | Adjustable-version feedback input, connected to the center point of the external resistor divider; the 0.8 V reference sets the regulation point and the absolute maximum is 6.0 V. |
| 5 | EN | input | Drive to logic-high to enable the IC, or to logic-low to disable it and enter micro-power shutdown mode; the absolute maximum is 19 V. |
| 6 | BS | passive | Bootstrap pin; a capacitor between LX and BS is required to form a floating supply for the high-side switch driver, with an absolute maximum of 25 V. |
