10 Power Supply Recommendations

The device is designed to operate from an input voltage supply range between 2.7 V and 5.5 V. This input supply must be well regulated. If the input supply is located more than a few inches from the TPS61169 device, additional bulk capacitance may be required in addition to the ceramic bypass capacitors.
