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
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.
