Atmel Corp. has debuted a family of 8-channel LED drivers with an integrated boost controller to deliver a complete power management system with patented Efficiency Optimiser (EO) to enhance power efficiency. The MSL3080/86/88 LED drivers are geared 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 per cent power efficiency for up to 20W LED backlit LCD.

When combined with Atmel AVR MCUs including tinyAVR and megaAVR MCUs, the devices claim to 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 synchronisation with LCD refresh such as small TVs 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.

Atmel's MSL3080/86/88 devices are available. 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.
