HT7660
HT7660 -- CMOS Switched-Capacitor Voltage Converter
General Description
HT7660 is a monolithic CMOS switched-capacitor voltage converter. HT7660 is designed to complete a voltage conversion from positive to negative. The only required external components are two low cost electrolytic capacitors.
HT7660 includes a voltage regulator, an RC oscillator and four output power MOS switches. The frequency of an RC oscillator can be lowered by adding an external capacitor between VDD and the OSC pin, or an external clock can be connected to the OSC pin to replace the original oscillator. The LV terminal may be tied to VSS to disable the voltage regulator. By doing this, low voltage operation can be improved.
