9 Power Supply Recommendations

The TPS40210-EP is designed to operate from an input voltage supply range between 4.5 V and 52 V. This input supply should remain within the input voltage range of the TPS40210-EP. If the input supply is located more than a few inches from the buck power stage controlled by the TPS40210-EP, additional bulk capacitance may be required in addition to ceramic-bypass capacitors. An electrolytic capacitor with a value of 100 uF is a typical choice.
