General Description
HT7660 is a monolithic CMOS switched-capaci-
tor voltage converter. HT7660 is designed to
complete a voltage conversion from positive to
negative. The only required external compo-
nents are two low cost electrolytic capacitors.
HT7660 includes a voltage regulator, an RC os-
cillator and four output power MOS switches.
The frequency of an RC oscillator can be low-
ered by adding an external capacitor between
V
DD
and the OSC pin, or an external clock can
be connected to the OSC pin to replace the origi-
nal oscillator. The LV terminal may be tied to
VSS to disable the voltage regulator. By doing
this, low voltage operation can be improved.
