MAX8742EAI+

Overview

The MAX8742EAI+ is a multi-output power supply controller designed for notebook applications. It operates with an input voltage range of 4.2V to 30V and provides three regulated outputs: 3.3V, 5V, and a variable output from 2.5V to 5.5V. The device features a fixed-frequency pulse-width-modulation (PWM) mode that is logic-controlled and synchronizable, helping to reduce noise and RF interference. It supports high or low side current sensing methods.

Feature Summary
