11 Power Supply Recommendations

TPS6131x is designed to operate from an input voltage supply from 2.5 V to 5.5 V. This input supply must be well regulated and capable to supply the required input current. If the input supply is placed far from the TPS6131x, additional bulk capacitance may be required to the ceramic bypass capacitors.
