IR's IR1168 SmartRectifier™IC Wins EDN Innovations Award 2010 for Best Component

Apr 28, 2010 | Market News

EL SEGUNDO, Calif. — International Rectifier, IR® (NYSE: IRF), a world leader in power management technology, today announced the IR1168 SmartRectifier™ IC for AC-DC power converters for high-end LCD TVs was voted best product in the Components category of the EDN Innovation Awards, 2010.

Now in its twentieth year, the annual EDN Innovation Awards honor outstanding engineering professionals and products.

The IR1168 SmartRectifier™ 200V dual smart secondary-side rectifier driver IC is designed to drive two N-Channel power MOSFETs used as synchronous rectifiers (SR) in resonant half-bridge topologies. Co-designed with IR's DirectFET® MOSFETs, which feature IR's latest Trench silicon and packaging technology, the IR1168-based solution delivers an efficiency improvement of 1.5 percent for a standard 240W LCD TV switch mode power supply (SMPS) and a reduction of rectifier device temperature of 25°C while shrinking board size by two thirds.

"As a leader in power management, IR is at the forefront of developing innovative energy efficient solutions to help meet our customer's design challenges. We are very pleased that in selecting the IR1168 SmartRectifier IC as Best Component, IR has received such strong support from the engineering community," said Adam White, IR's senior vice president, Worldwide Sales.

The IR1168, featuring IR's proprietary high-voltage IC technology, supports burst mode operation to deliver efficiency benefits even at light loads. Ruggedness and noise immunity are accomplished using an advanced blanking scheme and double-pulse suppression that allows reliable operation in fixed and variable frequency applications. Other key features include maximum 500kHz switching frequency, anti-bounce logic and UVLO protection, 4A peak turn-off gate drive current, micropower start-up and ultra low quiescent current, 10.7V gate drive clamp, 70ns turn-off propagation delay and a wide Vcc operating range from 8.6V to 18V.
