Atmel has announced a new family of 8-channel LED drivers with an integrated boost controller to deliver a complete power-management system for LCD backlighting applications. Atmel's MSL3080/86/88 LED drivers are well suited for industrial LCD-backlighting applications such as instrumentation, medical, avionics, military, kiosk, automotive, and rugged displays. The MSL3080/86/88 LED drivers also feature a proprietary control scheme delivering > 92% power efficiency for up to 20-W LED-back-lit LCD displays. Atmel's MSL3086/88 devices feature automatic string phasing that enables low EMI and eliminates audible noise. The MSL3088 LED driver offers a video sync input for applications that require synchronization with LCD refresh, such as small televisions and monitors, eliminating artifacts such as waterfall noise and ghosting effects. The MSL3080 driver allows designers to operate the internal current sinks in parallel for higher LED currents, up to 480 mA. "High power efficiency is a rapidly growing requirement in today's LED back-lit industrial and monitor LCD displays," said Miguel Mendoza, senior product marketing engineer at Atmel. "High performance industrial displays demand wide dimming range for all types of ambient-light conditions from low light to daylight [and] system- and fault-monitoring capabilities." Pricing and Availability Atmel's MSL3080/86/88 devices are available now. To help accelerate a designer's project, an Atmel MSL308X EV evaluation kit is also available. Pricing for 1,000-piece quantities start at US$1.98. Atmel MSL3086 product deeplink MSL3088 product deeplink
