MAX723ESE

Power Management - Specialized Overview

The MAX723ESE is a power supply management integrated circuit designed for palm-top computer and LCD applications. It integrates a step-up switching regulator, a low-dropout (LDO) linear regulator, and a charge pump to provide multiple voltage rails from a single lithium-ion battery source. The device operates with an input voltage range of 2.7V to 4.8V. It features a fixed output configuration for the boost section and includes protection mechanisms such as thermal shutdown and current limiting to ensure reliable operation in portable electronic systems.
