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.

FEATURES

• Lowest Output Impedance (Typical 35W at VIN=5V).

• Improved Direct Replacement for 7660.

• 1.5V to 6V Operation.

• No External Diode Required.

• Simple Conversion of +5V to -5V.

• Low Quiescent Current (Typical 36mA at VIN=5V).

• High Power Efficiency (Typical 98)

• Boost Pin for Higher Switching Frequency.

• Improved SCR Latchup Protection.

APPLICATIONS

• RS-232 Power Supplies.

• Handheld Instruments.

• Data Acquisition Systems.

• Supply Splitter, VOUT= ±VIN /2.

• Operational Amplifier Supplies.

• Panel Meter.
