MAX660 Datasheet CMOS Monolithic Voltage Converter

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 19-3293; Rev. 2; 9/96 CMOS Monolithic Voltage Converter _______________General.

General Description

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.

Greater than 90% efficiency over most of its load-current range bined with a typical operating current of only 120µA provides ideal performance for both battery-powered and boardlevel voltage conversion applications.
