Low-Cost Integrated Offset Logic

for Notebook CPU Power Supplies

General Description

Features

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.
