10 Power Supply Recommendations

The device is designed to operate with an input voltage supply from 4.5 V to 18 V. This input power supply must be well regulated. If the input supply is placed more than a few inches from the TPS65270 converter, bulk capacitance may be required in addition to the ceramic bypass capacitors. An electrolytic capacitor with a value of 47 µF is a typical choice.
