11 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 TPS53129 device, an additional 0.1 μF ceramic capacitance may be required in addition to the 10 μF of the ceramic bypass capacitors.
