9 Power Supply Recommendations

The TPS40180 VDD is designed from voltage supply range from 5 V to 15 V. Good regulation of this input supply is essential. The power stage input voltage range is from 2 V to 40 V. If the input supply is more distant than a few inches from the power stage, the circuit may requires bulk capacitance in addition to ceramic bypass capacitors.
