9 Power Supply Recommendations

TPS54060A is designed to operate from an input voltage supply range between 3.5 V and 60 V. This input supply should be well regulated. If the input supply is located more than a few inches from the TPS54060A 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.
