11 Power Supply Recommendations

The device is designed to operate from an input voltage supply range of TPS6108x's rating specification. This input supply must be well regulated. If the input supply is located more than a few inches from the converter, additional bulk capacitance may be required in addition to the ceramic bypass capacitors. An electrolytic or tantalum capacitor with a value of 47 μF is a typical choice.
