Atmel launches configurable 8-Channel LED Drivers

SAN JOSE, Calif. -- Atmel Corp.'s new family of 8-channel LED drivers feature an integrated boost controller to deliver a complete power management system with patented Efficiency Optimizer (EO) to enhance power efficiency for LCD backlighting applications.

The MSL3080/86/88 LED drivers target 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 LCD displays.

Flexibility, range
When designed in with Atmel AVR microcontrollers, the MSL3080/86/88 LED drivers provide designers 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 480mA.
