BacklightDriversSolutions Enhance Image Quality and Maximize Battery Life

Skyworks Solutions Inc., an innovator of high performance analog semiconductors enabling a broad range of end markets, introduced several new backlight LED drivers supporting next-generation smart phones and tablets.  Skyworks’ family of highly efficient, integrated, multi-channel products are tailored to support display panels ranging in size from 4 to 12 inches, significantly enhancing image quality and resolution while maximizing battery life.  The multi-channel architecture and highly efficient, DC/DC boost-technology enable LED backlight driver efficiencies exceeding 90 percent and facilitate superior dimming performance.

“Skyworks is excited to be offering smartphone and tablet providers a broad range of analog power management and lighting solutions,” said John O’Neill, vice president and general manager of power, lighting and display at Skyworks.  “The need for increasingly complex solutions to help meet consumers’ insatiable desire for longer battery life and better image quality from their mobile devices represents a strategic growth opportunity for Skyworks.  Given our broad product portfolio and in-house, RF and analog systems design expertise, Skyworks is uniquely positioned to address these needs particularly as our customers seek highly integrated architectures that deliver best-in-class performance.”

According to IHS iSuppli, shipments of smartphones with screens 5 inches or larger will more than double this year to over 60 million units in 2013 as consumers are increasingly attracted to larger screen sizes.  Currently, large-screen phones represent approximately 7 percent of the overall smartphone market.

Through its power management portfolio which includes LED flash and backlight drivers, discrete voltage regulators, PMICs and battery management devices, Skyworks is increasing its dollar content per platform in some of the fastest growing market segments.  With customers placing greater value on total solutions, Skyworks is creating highly integrated solutions and shortening development cycles for next-generation products.
