n DESCRIPTION
at 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 OUT = 2V IN ), divided (VOUT = VIN /2 ), or multiplied (V OUT = ±nV IN ), as shown in application examples.
The chip contains a series DC power supply regulator, oscillator, control circuitry and four output power MOS switches.
The frequency of oscillator c...
