The AIC1660 is a monolithic CMOS switched capacitor voltage converter. Designed to build an improved direct replacement for the popular 7660 and LTC1044, the main function of the AIC1660 is to convert a positive input voltage range of 1.5V to 6V to a corresponding negative output voltage range of -1.5V to -6V. The input voltage can also be doubled (VOUT = 2VIN) divided b...
