LED Drivers Provide Industry’s Most Complete Solutions with High Efficiency and Low EMI

Designers of high-performance automotive lighting applications now have a simpler, more efficient method for driving high-brightness LEDs (HBLEDs) with the MAX25610A and MAX25610B LED drivers from Maxim Integrated Products. The synchronous buck, buck-boost LED drivers/DC-DC converters offer a complete solution that features industry-leading EMI performance, without compromising on efficiency and size. These ICs drive up to eight HBLEDs directly from the automotive battery and integrate many external components to save on bill of materials (BOM) costs and space, making them excellent solutions for automotive lighting systems as well as industrial and commercial lighting applications.

They offer a wide input voltage range from 5V to 36V in buck-boost LED driver applications with up to 90 percent efficiency in buck-boost mode. These LED drivers have an internal current sense option and integrated high- and low-side switching MOSFETs to reduce solution space and cost. They offer programmable on-chip PWM dimming, which allows for fine dimming control without having to use a separate microcontroller. Additionally, the MAX25610B features a 2.2MHz switching frequency option allowing for an even more compact solution.
