TX4113

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).
