    Description

    The MAX1888 is a three-input decoder with three open-drain outputs. It is used with the MAX1718 or a similar DC-to-DC controller to offset the CPU core voltage in notebook computers. Designed to interface with low- voltage logic, the MAX1888 can program the controller for three independent offsets. The circuit is extremely low cost and is available in an 8-pin µMAX package.
