TX4310

XDS · DC-DC Converters · SOT-23-6

TX4310 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 output (4.8V-5.2V). Supplies up to 250mA at VIN=4.5V. Requires a low-ESR ceramic bypass capacitor of 10uF or larger.
2 GND power_in Device ground reference. Connect to the system ground plane with a short, low-inductance path.
3 EN input Enable input, active-high CMOS with a threshold of approximately 0.8V. Drive high to enable the charge pump, low to shut down. High-impedance CMOS input - must never be left floating.
4 C- passive Negative terminal of the external flying (bootstrap) capacitor for the charge pump. Use a low-ESR ceramic capacitor of at least 2.2uF; never use polarized (tantalum/aluminum) capacitors because the voltage can reverse at startup.
5 VDD power_in Device supply input, 2.7V to 5V. Bypass with a low-ESR ceramic capacitor of 10uF or larger close to the pin. Absolute maximum 6V.
6 C+ passive Positive terminal of the external flying (bootstrap) capacitor for the charge pump. Pair with C- (pin 4) using a >=2.2uF low-ESR ceramic capacitor.
