The Intersil 7660 is a CMOS Voltage Converter IC in an SMD package. The Intersil 7660 are monolithic CMOS power supply circuits that offer unique performance advantages over previously available devices. The 7660 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 and the 7660 does the same conversions with an input range of +1.5V to +12.0V resulting in complementary output voltages of -1.5V to -12.0V. Only 2 noncritical external capacitors are needed for the charge pump and charge reservoir functions. The ICL7660 can also be connected to function as voltage doubles and will generate output voltages up to +18.6V with a +10V input.
