7.3 Power Supply Recommendations

The VLOW and VHIHG power supply must be well regulated. If the power supply is located more than a few inches from the converter, additional bulk capacitance can be required in addition to the ceramic bypass capacitors. A typical choice is an electrolytic or tantalum capacitor with a value of 47μF.
