9 Power Supply Recommendations

The devices are designed to operate from an input voltage supply range between 4.5 and 24 V. This input supply must be well regulated. If the input supply is located more than a few inches from the TPS53128 device, an additional 0.1 μF ceramic capacitance may be required in addition to the 10 μF of the ceramic bypass capacitors.
