DESCRIPTION

The AIC1660 is a monolithic CMOS switched

capacitor voltage converter. Designed to be an

improved direct replacement for the popular 7660

and LTC1044, the main function of the AIC1660 is

to convert a positive input voltage in the range of

1.5V to 6V to the corresponding negative output

voltage in the range of -1.5V to -6V. The input

voltage can also be doubled (V

divided (V

The chip contains a series DC power supply

regulator, oscillator, control circuitry and four

output power MOS switches. The frequency of

oscillator can be lowered by the addition of an

external capacitor to the OSC pin, or the oscillator

may be over-driven by an external clock.

The boost function is available to raise the

oscillator frequency to optimize performance in

specific applications. The “LV” terminal may be

tied to GND to improve low input voltage (V

larger than 3V to improve power dissipation.

The AIC1660 provides performance superior to

previous designs by combining low output

impedance, low quiescent current with high

efficiency, and by eliminating diode drop voltage

losses. The only required external components

are two low cost electrolytic capacitors.
