Product Overview

The LTC1044CN8#PBF is a switched capacitor Voltage Converter provides several voltage conversion functions, the input voltage can be inverted (VOUT=-VIN), doubled (VOUT=2 VIN), divided (VOUT=VIN/2) or multiplied (VOUT=±nVIN). Designed to be pin-for-pin and functionally compatible with the popular 7660, the LTC1044 provides significant features and improvements over earlier 7660 designs. These improvements include full 1.5 to 9V supply operation over the entire operating temperature range without the need for external protection diodes, 21/2 times lower quiescent current for greater power conversion efficiency and a "boost" function to raise the internal oscillator frequency to optimize performance in specific applications. Although the LTC1044 provides significant design and performance advantages over the earlier 7660 device, it still maintains its compatibility with existing 7660 designs.
  • Plug-in compatible with 7660 with these additional features
  • Guaranteed operation to 9V with no external diode, over full temperature range
  • Boost pin (pin 1) for higher switching frequency
  • Lower quiescent power
  • Efficient voltage doubler
  • 200µA Maximum no load supply current at 5V
  • 97% Minimum open circuit voltage conversion efficiency
  • 95% Minimum power conversion efficiency
  • Wide operating supply voltage range
  • Easy to use
