MAX660 Datasheet (Maxim) - CMOS Monolithic Voltage Converter

MAX660, CMOS Monolithic Voltage Converter

The MAX660 monolithic, charge-pump voltage inverter converts a +1.5V to +5.5V input to a corresponding -1.5V to -5.5V output.

Using only two low-cost capacitors, the charge pump’s 100mA output replaces switching regulators, eliminating inductors and their associated cost, size, and EMI.
