Austria microelectronics released a new energy-saving LED controller IC AS3693B

Austria Microelectronics (SWX Stock Code: AMS) for a new generation of LCD TV backlight launched 16 channel LED controller IC AS3693B, extended its LED drive and controller product line.

The innovative AS3693B LED controller IC helps slim LCD TV to achieve the highest possible contrast, so as to achieve the best picture quality. The concept of external FET control and active regulation of LED power supply power saving technology can minimize the power consumption of the system. This not only makes the design of ultra-thin panels possible, but also to achieve a very energy-efficient TV solutions. AS3693B LED controller IC specially designed to achieve the perfect synchronization of the LCD screen and the LED backlight unit, in order to achieve the desired image quality of the block dimming control".

Austria microelectronics AS3693B high precision LED controller IC can manage 16 LED channels, each channel current accuracy is 0.5%, which is the industry's best performance so far. High precision LCD backlight can achieve the most accurate color and brightness control. At the same time, some new features, such as "reverse PWM" and so on, provide new possibilities for controlling the different LED blocks of the backlight unit.

Austria microelectronics LED backlight driver market manager Markus Luidolt said: "by LCD OEM and industry partners, we have developed a new AS3693B LED backlight solution will reverse PWM's function in advance to the market. We are proud to be an innovator in this fast growing market, bringing new energy saving concepts and excellent overall system performance to the industry. "

AS3693B uses ePTQFP64 10X10mm package.
