The MAX25612/MAX25612B is a single-channel high-brightness LED (HB LED) driver for automotive front-light applications such as high beam, low beam, daytime running light (DRL), turn indicator, fog light and other LED lights. It can take an input voltage from 5V to 48V and can drive a string of LEDs with a maximum output voltage of 65V. The MAX25612/MAX25612B is fully synchronous and is suitable for boost and buck-boost applications that need synchronous rectification providing efficiencies greater than 90%. The MAX25612/MAX25612B senses output current at the high side of the LED string. High-side current sensing is required to protect against shorts from the output to the ground or battery input. It is also the most flexible scheme for driving LEDs, allowing boost, high-side buck, or buck-boost mode configurations. The PWM input provides LED dimming ratios of up to 5000:1, and the ICTRL input provides additional analog dimming capability in the MAX25612/MAX25612B. The MAX25612/MAX25612B also includes a active-low FLT flag that indicates open string, shorted string, and thermal shutdown. The MAX25612/MAX25612B has built-in spread-spectrum modulation for improved electromagnetic compatibility performance. The MAX25612/MAX25612B is available in a space-saving (4mm x 4mm), 20-pin side-wettable TQFN or a 20-pin TSSOP package and is specified to operate overthe -40°C to +125°C automotive temperature range.
