TX4101

XDS · DC-DC Converters · SOT-23-5

TX4101 from XDS, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 EN input Enable input, active high. Drive above 1.5V to enable the converter; below 0.6V forces shutdown (shutdown current <1µA). Must not be left floating.
2 GND power_in Chip ground / return reference for both the analog control and power stage.
3 SW output Switch node output. Internally tied to the drain of the synchronous power MOSFET; connect to the external inductor. Rated for 1.3A peak switch current.
4 VDD power_in Main supply input, 2.5-5.5V (3.4-5.5V for the G33 3.3V variant). Bypass to GND with a 10µF ceramic capacitor.
5 VOUT/FB input Feedback / output sense pin. On fixed-voltage variants (G12/G15/G18/G33), connect directly to VOUT for internal regulation. On the ADJ variant, tie to the mid-point of an external resistor divider from VOUT to GND; regulation target is VFB = 0.6V (VOUT = 0.6V x (1 + R1/R2)). Feedback bias current ±30nA typ.
