LTC1044 Datasheet PDF

●The LTC1044AIS8#PBF is a monolithic CMOS switched-capacitor charge-pump Voltage Converter plugs in for LTC1044 in applications where higher input voltage (up to 12V) is needed. The LTC1044A provides several conversion functions without using inductors. 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+.

● Boost pin (pin 1) for higher switching frequency

● 97% Minimum open circuit voltage conversion efficiency

● 95% Minimum power conversion efficiency

● 200µA Maximum no load supply current at 5V
