MAX878 Datasheet (Maxim) - Step-Up/Step-Down DC-DC Converters

MAX878, 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
