Introduction

AI Translation

The MAX1762/MAX1791 PWM step-down controllers provide high efficiency, excellent transient response, and high DC output accuracy needed for stepping down high-voltage batteries to generate low-voltage CPU core, I/O, and chipset RAM supplies in notebook computers and PDAs. The standard application circuit generates a low-voltage output for general-purpose use in notebook computers (I/O supply, fixed CPU, core supply, and DRAM supply). This DC-DC converter steps down battery voltage from 5V to 20V with high efficiency and accuracy to a fixed voltage of 1.8V/2.5V/adj (MAX1762) or 3.3V/5.0V/adj (MAX1791).
