New LED controller IC cuts power dissipation in flat LCD TVs

Austriamicrosystems, a leading global designer and manufacturer of high performance analog ICs, has extended its portfolio of specialized LED drivers and controllers for the latest generation of LCD TV backlighting with the AS3693B 16 channel LED controller IC.



The innovative AS3693B LED controller IC helps to build extremely flat LCD TVs with highest possible contrast ratios, resulting in best picture quality. The concept of controlling external FETs and the patented power saving technology, which actively regulates the LED power supply, both minimize power dissipation in the system. This makes very flat panel designs possible and enables the creation of very energy efficient TV solutions. The AS3693B LED controller IC is especially designed to allow perfect synchronization of the LCD picture and the LED backlight unit in order to realize so called "block dimming control" for outstanding picture quality.

The AS3693B high precision LED controller IC manages 16 LED cannels, each with a current accuracy of 0.5 percent. This is by far the best performance in the industry today. The high level of accuracy enables the most exact color and brightness control of the LCD backlights currently available. In addition, new features like "reverse PWM" create entirely new possibilities to control different LED segments of the backlighting unit. The AS3693B is available in an ePTQFP64 10mm x 10mm package.

Markus Luidolt, marketing manager for LED backlight drivers at Austriamicrosystems, commented as the AS3693B, their latest LED backlighting solution, in close partnership with their OEM partners in the LCD industry bringing newest features like reverse PWM to the market early. They are proud to take the innovator's position in this booming market with new power saving concepts and outstanding total system performance.

It’s disclosed that at CES 2009 in Las Vegas, Jan 8th to Jan 11th, Austriamicrosystems will present its entire portfolio of LED backlighting solutions and demonstrate its latest LCD TV LED backlight implementation in an off-exhibition suite.
