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 (VOUT = 2VIN ), divided (VOUT = VIN /2 ), or multiplied (VOUT = ±nVIN ), as shown in application examples.
