Configurable 8-channel LED driver family supports monitors and industrial LCD panel backlighting

October 02, 2012 // By Paul Buckley
Atmel Corporation has introduced a new family of 8-channel LED drivers with an integrated boost controller to deliver a complete power management system with patented Efficiency Optimizer (EO) to enhance power efficiency for LCD backlighting applications.

Atmel’s MSL3080/86/88 LED drivers are 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 20 W LED backlit LCD displays.

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.

Atmel’s 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 480 mA.  

Availability and Pricing

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 $1.98.
