10 Power Supply Recommendations

The TPS65631W is designed to operate from an input voltage supply range between 2.9 V and 4.5 V. If the input supply is located more than a few centimeters from the TPS65631W additional bulk capacitance may be required. The 10 µF shown in the schematics in this data sheet is a typical choice for this function.
