HT7660

CMOS Switched-Capacitor Voltage Converter

Features

No external diode required

Simple conversion of V_DDto -V_DD

Typically with no load voltage conversion, 99.9% effi-

ciency

Cascade connection (two devices are connected,

_OUT= -2 V_DD)

Typical power efficiency is 98%

Wide operating voltage range: 3V to 12V

8-pin DIP/SOP package

Boost pin for higher switching frequency

Easy to use

Requires only two external capacitors

Applications

RS-232 power supply

Operation amplifier supply

Data acquisition systems

Positive voltage doubler

On board negative supply for dynamic RAMS

Supply voltage splitter, V_O= ± V_DD/2

General Description

HT7660 is a monolithic CMOS switched-capacitor volt-

age converter. HT7660 is designed to complete a volt-

age conversion from positive to negative. The only

required external components are two low cost electro-

lyticcapacitors.

an RC oscillator can be lowered by adding an external

capacitor between V_DDand 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.

HT7660 includes a voltage regulator, an RC oscillator

and four output power MOS switches. The frequency of
