... The AIC1660 is a monolithic CMOS switched capacitor voltage converter. Designed 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. the corresponding negative output voltage in the range of -1.5V to -6V. The input ...
