Schematic Volt

1 2 volts power supply

This switch mode power supply circuit require an input voltage range , between 4.5V to 16V,and will provide a very stable output voltage of 1.2 volt . The LTM4627 supports an output voltage range of 0.6V to 5V, set by a single external resistor , so you can modify the output voltage .

High switching frequency and a current mode architecture enable a very fast transient response to line and load changes without sacrificing stability.
