7.3 Power Supply Recommendations

The device is designed to operate from an input voltage supply range between 1.8V to 5.5V. 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. A typical choice is a tantalum or aluminum electrolytic capacitor with a value of 100µF. Output current of the input power supply must be rated according to the supply voltage, output voltage, and output current of the TPSM81033.
