Product Summary

The ICL7662CPA is a monolithic high-voltage CMOS power supply circuit which offers unique performance advantages over previously available devices. The ICL7662CPA performs supply voltage conversion from positive to negative for an input range of +4.5V to +20.0V, resulting in complementary output voltages of -4.5V to -20V. Only 2 noncritical external capacitors are needed for the charge pump and charge reservoir functions. The ICL7662CPA can also function as a voltage doubler, and will generate output voltages up to +38.6V with a +20V input. The applications of the ICL7662CPA include On Board Negative Supply for Dynamic RAMs, Localized μprocessor (8080 Type) Negative Supplies, Inexpensive Negative Supplies, Data Acquisition Systems and Up to -20V for Op Amps.
