9 Power Supply Recommendations

The design of the device is for operation from an power supply range between 3.5 V and 60 V. It is essential that the power supply voltage remains within this range. If the power supply is more distant than a few inches from the TPS54060 converter, the circuit may require additional bulk capacitance besides the ceramic bypass capacitors. An electrolytic capacitor with a value of 100 µF is a typical choice.
