The Atmel Corporation has developed a new family of 8-channel LED drivers that come with an integrated boost controller and delivers a complete power management system with a patented Efficiency Optimizer (EO) that will enhance power efficiency for LCD backlighting applications. The MSL3080/86/88 LED drivers are suitable for industrial LCD backlighting applications such as instrumentation, medical, avionics, military, kiosk, automotive and rugged displays.
These new MSL3080/86/88 LED drivers also feature a proprietary control scheme and a robust design that delivers over 92 percent power efficiency for up to 20W LED backlit LCD displays.
When combined with Atmel’s AVR microcontrollers (MCUs), including tinyAVR and megaAVR MCUs, the MSL3080/86/88 LED drivers provide a high 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 also feature automatic string phasing that enables low electromagnetic interference (EMI) and eliminates audible noise. They also offer video sync input for applications that require synchronisation 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.
“High power efficiency is a rapidly growing requirement in today”s LED backlit industrial and monitor LCD displays,” said Miguel Mendoza, sr. product marketing engineer at Atmel Corporation. “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.”
