10 Power Supply Recommendations

The devices are designed to operate from an input supply range between 4.5 V and 17 V. This input supply must be well regulated. If the input supply is located more than a few inches from the TPS566250 device, additional bulk capacitance may be required in addition to the ceramic bypass capacitors.
