6 Power Supply Recommendations

The devices are designed to operate from an input voltage supply range between 4.5 V and 24 V. This input supply must be well regulated. If the input supply is located more than a few inches from the TPS53124 device additional 0.1 µF ceramic capacitance may be required in addition to the ceramic bypass capacitors, 10 µF.
