LED driver ICs from Austriamicrosystems now powers LG Electronics LED backlit TVs

Austriamicrosystems has announced that its AS3693A and AS3693B LED driver ICs now powers LG Electronics new LED backlit TVs being introduced at CES 2010.

The AS3693 family facilitates flat LCD TVs with high contrast ratios resulting in high picture quality. A patented power saving technology actively regulates the LED power supply and minimizes power dissipation in the system. This makes very thin flat panel designs with high brightness uniformity.

The AS3693A is a 16 channels high precision LED driver with built-in PWM generators for building backlight panels in LCD-TV-sets.

The AS3693B is a 16 channels high precision LED controller with built-in PWM generators for driving external FETs in LCD-backlight panels.

External clock and synchronizing inputs allow the synchronization of the LCD backlight with the TV picture. Local dimming and scan dimming is supported by 16 independent PWM generators with programmable delay, period and duty cycle.

Three free configurable dynamic power feedback circuits make the device usable for white LED as well as RGB backlights. Built-in safety features include thermal shutdown as well as open and short LED detection. All circuit parameters are programmable via I²C or SPI interface.

"We are very proud of this intense cooperation and are fully committed to delivering best-in-class performance, cost-effective solutions and the most energy efficient technology to LG Electronics. Austriamicrosystems' AS3693 enabled LG Electronics to develop a very slim design with superb picture quality while at the same time achieving extremely low energy consumption. We will continuously innovate to further drive product designs in this fast growing market," Markus Luidolt, marketing manager lighting at austriamicrosystems, stated.
