DESCRIPTION
The LTC1044A is a monolithic CMOS switched-capacitor voltage converter. It plugs in for ICL7660/LTC1044 in applications where higher input voltage (up to 12V) is needed. The LTC1044A provides several conversion functions without using inductors. The input voltage can be inverted (VOUT = – VIN), doubled (VOUT = 2VIN), divided (VOUT = VIN/2) or multiplied (VOUT = ±nVIN).FEATURES
■ 1.5V to 12V Operating Supply Voltage Range■ 13V Absolute Maximum Rating
■ 200µA Maximum No Load Supply Current at 5V
■ Boost Pin (Pin 1) for Higher Switching Frequency
■ 97% Minimum Open Circuit Voltage Conversion Efficiency
■ 95% Minimum Power Conversion Efficiency
■ IS = 1.5µA with 5V Supply When OSC Pin = 0V or V +
■ High Voltage Upgrade to ICL7660/LTC1044
APPLICATIONS
■ Conversion of 10V to ±10V Supplies■ Conversion of 5V to ±5V Supplies
■ Precise Voltage Division: VOUT = VIN/2 ±20ppm
■ Voltage Multiplication: VOUT = ±nVIN
■ Supply Splitter: VOUT = ±VS/2
■ Automotive Applications
■ Battery Systems with 9V Wall Adapters/Chargers
