10 Power Supply Recommendations

The LM2662/LM2663 is designed to operate from as an inverter over an input voltage supply range between 1.5 V and 5.5 V when the LV pin is grounded. This input supply must be well regulated and capable to supply the required input current. If the input supply is located far from the LM2662/LM2663 additional bulk capacitance may be required in addition to the ceramic bypass capacitors.
