Nov 16, 2010 Austriamicrosystems has announced the AS3696, a new 4-channel LED driver IC that ensures the brightest and most brilliant video images and enables best possible 3D effects in slimmest LCD TVs.
With a channel-to-channel accuracy +/-1 %, the AS3696 BLU driver IC is a precision LED controller with PWM inputs and internal PWM generators. It is designed for driving external FETs in LCD backlight panels, allowing long LED strings and the high currents used in 3D mode. It offers the functions and accuracy to simplify the design task of LED driving with an on-chip shunt regulator and built-in safety features, including thermal shutdown and open and short LED detection. In addition, the AS3696 LED driver IC also provides a unique power feedback regulation for controlling external power supplies to reduce power and achieve the highest system efficiency in LED backlit LCD TVs.
Samples of the AS3696 BLU Driver IC are available now. The 1,000 piece price for the AS3696 QFN32 is $1.50 USD; the AS3696 TQFP32 is $1.70.
