XDS · DC-DC Converters · SOT23-6
TX4113 from XDS, in a SOT23-6. 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 | BS | passive | Bootstrap capacitor pin, connected between SW and BS to supply the high-side driver; BS is limited to (VSW - 0.3V) to (VSW + 5V). |
| 2 | GND | power_in | Ground pin; the datasheet recommends a large copper area on GND to cool the chip. |
| 3 | FB | input | Feedback/voltage regulation pin that connects to the external divider (R1/R2) and is compared to the 0.6V internal reference; absolute maximum is -0.3V to 6V. |
| 4 | EN | input | Chip enable pin; the device starts when EN and VIN are above their thresholds, and pulling EN low shuts the chip down; absolute maximum is -0.3V to 17V. |
| 5 | VIN | power_in | Power input pin, absolute maximum -0.3V to 17V, with a stated operating input range of 4.5V to 16V (electrical table lists 3.3V minimum). |
| 6 | SW | output | Switch node driven by the internal high-side and low-side MOSFETs; absolute maximum is -0.3V to (VIN + 0.5V). |
