LTC1044A 12V CMOS Voltage Converter
To optimize performance in specific applications, a boost function is available to raise the internal oscillator frequency by a factor of 7. 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 +
