9 Power Supply Recommendations

The TPS61162A and TPS61163A are designed to operate from an input supply range of 2.7 V to 6.5 V. This input supply should be well regulated and be able to provide the peak current required by the LED configuration and inductor selected without voltage drop under load transients (start-up or rapid brightness change). If the input supply is located far from the TPS6116xA additional bulk capacitance may be required in addition to the ceramic bypass capacitors.
