MAX8743 Overview
The MAX8743 is a dual pulse-width modulation (PWM) controller configured for step-down (buck) topologies that provides the high efficiency, excellent transient response, and high DC output accuracy necessary for stepping down high-voltage batteries to generate lowvoltage chipset and RAM power supplies in notebook puters. The CS_ inputs can be used with low-side sense resistors to provide accurate current limits or...
