IR’s Energy-Efficient IRS2548D and DirectFET®plus Power MOSFETS Win Top Industry Awards in China for Innovation

EL SEGUNDO, Calif. -- (BUSINESS WIRE) -- International Rectifier, IR^® (NYSE: IRF), a world leader in power management technology, today announced that its IRS2548D LED Driver IC and IRF6811 and IRF6894 DirectFET®plus power MOSFETs have won awards from EDN China and Electronic Engineering & Product World (EEPW) respectively.

IR’s IRS2548D LED control IC was awarded “Leading Product” in the 2011 EDN China Innovation Awards in the Power Device and Module – LED category. The IRS2548D Switched Mode Power Supply (SMPS) control IC for energy efficient applications for high power Light Emitting Diode (LED) illumination including LED street lighting, stadium lighting and theatrical lighting combines Power Factor Correction (PFC) and half-bridge driver in a single IC. The device offers greater than 88 percent efficiency for a 40 V / 1.3 A HBLED load to deliver a higher efficiency solution compared to alternative Flyback converter solutions at power levels above 60 W.

Additionally, the IRF6811 and IRF6894 DirectFET®plus power MOSFETs have been named “Best Energy Conservation Solution” at the EEPW Editor’s Choice Awards. The DirectFET®plus power MOSFETs feature IR’s new generation of silicon that sets a new standard in efficiency for 12V input synchronous buck applications including next-generation servers, desktops, and notebooks. The IRF6811 and IRF6894, reduce on-state resistance (Rds(on)) and gate charge (Qg) compared to previous generation devices to significantly improve efficiency up to 2 percent. In addition, the devices offer ultra-low gate resistance (Rg) enabling further efficiency improvement by minimizing switching losses in DC-DC converters.

“With our mission to develop innovative power management products and our commitment to supporting green engineering in China, we are delighted to receive such prestigious awards for our energy-efficient IRS2548D LED driver IC and IRF6811 and IRF6894 DirectFET®plus power MOSFETs,” said Adam White, IR’s Senior Vice President, Worldwide Sales.
