9 Power Supply Recommendations

The devices are designed to operate from an input supply ranging from 4.5 V to 28 V. The input supply should be well regulated. If the input supply is located more than a few inches from the converter an additional bulk capacitance typically 100 µF may be required in addition to the ceramic bypass capacitors.
