5V/3.3V/3V/Adjustable-Output, Step-Up/Step-Down DC-DC Converters

General Description The MAX877/MAX878/MAX879 are pulse-skipping, step-up/step-down DC-DC converters that provide a regulated output from inputs both above and below the output. They require only three external components—an inductor (typically 22μH) and two filter capacitors. Features ? Regulat
