HT7660 Description

HT7660 is a monolithic CMOS switched-capacitor voltage converter. HT7660 is designed to complete a voltage conversion from positive to negative. The onlyrequired external components are two low cost electrolytic capacitors.HT7660 includes a voltage regulator, an RC oscillatorand four output power MOS switches. The frequency ofan RC oscillator can be lowered by adding an externalcapacitor between VDD and the OSC pin, or an externalclock can be connected to the OSC pin to replace theoriginal oscillator. The LV terminal may be tied to VSS todisable the voltage regulator. By doing this, low voltageoperation can be improved.
