9 Power Supply Recommendations

The devices are designed to operate from an input voltage supply range between 2.5V and 5.5V. If the input supply is located more than a few inches from the device, an additional bulk capacitance may be required in addition to the ceramic bypass capacitors. An electrolytic capacitor with a value of 47µF is a typical choice.

The average input current of the TPS62095 is calculated as:
