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).

To optimize performance in specific applications, a boost function is available to raise the internal oscillator frequency by a factor of seven. Smaller external capacitors can be used in higher frequency operation to save board space. The internal oscillator can also be disabled to save power. The supply current drops to 1.5μA at 5V input when the OSC pin is tied to GND or V+.

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
