MAX877 - 5V/3.3V/3V/Adjustable-Output / Step-Up/Step-Down DC-DC Converters
The MAX877/MAX878/MAX879 are pulse-skipping, stepup/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.
The MAX877 delivers a regulated 5V o
