HTC KOREA LM7660

The LM7660 is a monolithic CMOS power supply circuit which offers unique performance advantages over previously available devices. The LM7660 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. The LM7660 can also be connected to function as voltage doublers and will generate output voltages up to +18.6V with a +10V input.

DESCRIPTION

Only two noncritical external capacitors are needed for the charge pump and charge reservoir functions. Contained on the chip are a series DC supply regulator, RC oscillator, voltage level translator, and four output power MOS switches. A unique logic element senses the most negative voltage in the device and ensures that the output N-Channel switch source-substrate junctions are not forward biased.
