10 Power Supply Recommendation
The devices are designed to operate from an input voltage supply range between 4.5 V and 60 V. This input
supply should be well regulated. If the input supply is located more than a few inches from the TPS54560
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.
