Unterpremstaetten, Austria - austriamicrosystems extends 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 AS3693B LED controller IC enables designers to build extremely flat LCD TVs with highest possible contrast ratios and best picture quality.
It controls external FETs while the patented power-saving technology regulates the LED power supply, with the result that power dissipation in the system is minimized. The company states that these technologies make very flat panel designs possible and enable the creation of highly energy-efficient TV solutions.
The new controller IC is designed to allow perfect synchronization of the LCD picture and the LED backlight unit in order to realize "block dimming control" for outstanding picture quality.
The AS3693B manages 16 LED channels, each with an current accuracy of 0.5%. The high level of accuracy enables exact color and brightness control of the LCD backlight. A new feature called "reverse PWM" allows control of different LED segments of the backlighting unit.
The AS3693B is available in an ePTQFP64 10x10 mm package. For more information about the LED Driver Portfolio visit www.austriamicrosystems.com
(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.)
