The LTC1044A is a monolithic CMOS switched capacitor voltage converter. The header is required for the ICL7660/LTC1044 in higher input voltage (up to 12V) applications. The LTC1044A offers several inductors that are not used by the transfer function. The input voltage can be doubled (VOUT = VIN) (VOUT = 2VIN), divided (VOUT = VIN/2) or multiplied (VOUT = ± nVIN). To optimize performance in specific applications, the boost function can be used to increase the frequency of the internal oscillator by a factor of 7. Smaller external capacitors can be used at higher frequencies to save board space. The internal oscillator can also be disabled to save power. Supply current drops to 1.5mA at 5V input when OSC pin is tied to GND or V+.
