TX4314

XDS · DC-DC Converters · SOT-23-6

TX4314 from XDS, in a SOT-23-6. 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 VOUT power_out Regulated 5V charge-pump output (typ. 4.94V, 4.8-5.1V). Rated for up to 110mA with VIN >= 3V and 230mA with VIN >= 3.6V. Bypass to GND with a low-ESR ceramic capacitor (>=2.2uF, 10uF typical); tolerates continuous short to GND.
2 GND power_in Chip ground / return for input, output and flying capacitors. Should be connected to a solid ground plane with short traces to the bypass capacitors to minimize switching noise.
3 EN input Active-high CMOS enable input (threshold ~0.8V, typ. VIN/2). Drive high to enable the charge pump; drive low to enter shutdown (ISHDN ~0.2uA, VOUT disconnected from VIN). High-impedance input must NEVER be left floating.
4 C- passive Negative terminal of the external flying (bootstrap) capacitor for the charge pump. Connect a >=2.2uF (10uF typical) low-ESR ceramic capacitor between C+ and C-. Do NOT use polar capacitors (tantalum/aluminum) as the voltage may reverse during startup.
5 VDD power_in Chip supply input, 2.7V to 4.5V operating range (absolute max 6V). Bypass to GND with a low-ESR ceramic capacitor (>=2.2uF, 10uF typical) placed close to the pin.
6 C+ passive Positive terminal of the external flying (bootstrap) capacitor for the charge pump. Connect a >=2.2uF (10uF typical) low-ESR ceramic capacitor between C+ and C-. Polar capacitors are prohibited.
