9 Power Supply Recommendations

The devices are designed to operate from an input voltage supply range between 4.5 V and 60 V. If the input supply is located more than a few inches from the TPS54560B-Q1 converter additional bulk capacitance may be required in addition to the ceramic bypass capacitors. An electrolytic capacitor with a value of 100 μF is a typical choice.
