Product Summary

The ICL7662CPA is a CMOS voltage converter. The ICL7662CPA is a monolithic charge pump voltage inverter that will convert a positive voltage in the range of +4.5V to +20V to the corresponding negative voltage of -4.5V to -20V. The ICL7662CPA provides performance far superior to previous imple-mentations of charge pump voltage inverters by combining low quiescent current with high efficiency. The ICL7662CPA has an oscillator, control circuitry, and 4 power MOS switches on-chip, with the only required external components being two low cost capacitors.Applications of the ICL7662CPA are Inexpensive Negative Supplies, Data Acquisition Systems, Up to -20V for Op Amps, and Other Linear Circuits, Supply Splitter, V0UT = Vs/2 RS-232 Power Supplies.
