Display backlighting using high-brightness LEDs and SEPIC power modules

Posted: 04 Mar 2009 ?? ?Print Version ?Bookmark and Share

Keywords:LED high brightness? module SEPIC? backlighting display?

In automotive applications, offering a wide dimming ratio for backlights is important because the display panel must be viewable in both direct sunlight and in complete darkness. The latest high-brightness (HB) LEDs offer a backlighting solution that provides a wider dimming ratio, better reliability, and lower power consumption than CCFLs. SEPIC power converters provide a flexible and power-efficient solution for driving strings of HB LEDs, while permitting a wide, 4000:1 dimming ratio. This article discusses the use of SEPIC power modules and the MAX16807/MAX16808 HB LED drivers to deliver a wide-dimming-ratio backlight solution.
