AIC1660
Switched-Capacitor Voltage Converter
n FEATURES
l
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.
