MAX879 converters equivalent, step-up/step-down dc-dc converters.
o Regulates from Inputs Above & Below the Output o 1V to 6.2V Supply-Voltage Range o Internal 1A Active Rectifier with Input-to-Output Disconnect in Shutdown o Up to 210m.
Two or Three NiCd Cells to 3V/3.3V Conversion Three or Four Alkaline Cells to 5V Conversion One Lithium Cell to 3V/3.3V .
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 capaci.
