Atmel – Highly-configurable 8-channel LED driver for monitors and LCD panel backlighting (MSL3080)Oct 2 2012 - Power [More Power Articles]
Atmel has announced a new family of 8-channel LED drivers with an integrated boost controller to deliver a complete power management system, with a patented ‘efficiency Optimizer’ (EO) to enhance power efficiency for LCD backlighting applications.
The MSL3080/86/88 LED drivers are seen as ideal for industrial LCD backlighting applications such as instrumentation, medical, avionics, military, kiosk, automotive and rugged displays.
The MSL3080/86/88 LED drivers also feature proprietary control scheme and robust design delivering greater than 92 percent power efficiency for up to 20W LED backlit LCDs.
When combined with Atmel AVR microcontrollers (MCUs), including tinyAVR and megaAVR MCUs, the MSL3080/86/88 LED drivers provide an unprecedented degree of flexibility, comprehensive fault and system monitoring as well as over 5000:1 PWM dimming range for the most demanding applications.
The MSL3086/88 devices feature automatic string phasing that enables low electromagnetic interference (EMI) and eliminates audible noise. The MSL3088 LED driver offers 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 480mA, says the company.
“High power efficiency is a rapidly growing requirement in today’s LED backlit industrial and monitor LCD displays,” said Miguel Mendoza, senior product marketing engineer, Atmel. “High performance industrial displays demand wide dimming range for all types of ambient light conditions from low light to daylight, system and fault monitoring capabilities. The MSL3080/86/88 product family allows our customers to design display solutions to achieve these requirements.”More news from Atmel
