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.
