9 Power Supply Recommendation

This device is designed to operate from an input voltage supply range between 4.5 V and 65 V. The input supply should be well regulated. If the input supply is located more than a few inches from the TPS92511 application board, additional bulk capacitance may be required in addition to the input capacitor. A ceramic capacitor with a value of 2.2 μF is a typical choice.
