ICL7660 CMOS Voltage Converters The ICL7660 is a monolithic CMOS power supply circuit that offers unique performance advantages over previously available devices. The ICL7660 performs supply voltage conversions from positive to negative for an input range of +1.5V to +10.0V resulting in complementary output voltages of -1.5V to -10.0V. Only two noncritical external capacitors are needed for the charge pump and charge reservoir functions. The ICL7660 can also be connected to function as voltage doublers and can generate output voltages up to +18.6V with a +10V input. Contained on the chip are a series DC supply regulator, RC oscillator, voltage level translator, and four output power MOS switches.
