HTC KOREA TJ7660
TJ7660 is a monolithic CMOS power supply circuit which offers unique performance advantages over previously available devices. The TJ7660 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 TJ7660 can also be connected to function as voltage doublers and will generate output voltages up to +18.6V with a +10V input.| Part No. | TJ7660 |

DESCRIPTION
The HTC Only 2 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.
