MAX1534ETE+

Power Supply Controllers, Monitors Overview

The MAX1534ETE+ is a high-efficiency, triple-output power management IC designed for notebook computers. It integrates one step-down DC-DC converter and two low-dropout (LDO) regulators. The device operates from an input voltage range of 4.5V to 24V. It features a keep-alive power supply capability to maintain system state during sleep modes. The buck regulator provides up to 500mA output current. The component functions within a temperature range of -40°C to +85°C or +105°C depending on specific variant documentation, housed in a 16-pin TQFN package with an exposed pad.
