MAX25612 High-Voltage LED Controller

Analog Devices Inc. MAX25612 High-Voltage LED Controller is a single-channel high-brightness LED (HB LED) driver for automotive front-light applications. These applications include high beam, low beam, daytime running lights (DRL), turn indicators, fog lights, and other LED lights. It can take an input voltage from 5V to 48V and drive a string of LEDs with a maximum output voltage of 65V. The MAX25612 is fully synchronous and is suitable for boost and buck-boost applications that need synchronous rectification, providing efficiencies greater than 90%.
