Atmel unveiled a new family of intelligent multistring LED drivers for the backlighting and solid state lighting markets. The devices enable LCD TVs to achieve a 10M:1 dynamic contrast and low motion blur. They also provide over 10000:1 PWM dimming range for PC monitors and industrial displays. In solid state lighting applications, the drivers, together with Atmel microcontrollers, allow dynamic white-point setting, colour mixing and networked lighting with ZigBee, DALI and other standards. Other features include comprehensive fault management, LED ageing and thermal control, and programmability with the on-chip EEPROM, as well as scalability to any number of LED strings with minimal DC-to-DC converters.
