EL SEGUNDO, Calif. — International Rectifier, IR® (NYSE: IRF), a world leader in power management technology, today announced that the company’s SupIRBuck® portfolio of versatile wide input, single output integrated point-of-load (POL) DC-DC voltage regulators has won a "Top 10 DC-DC Award" from Electronic Products China magazine.

SupIRBuck integrates IR’s co-designed high performance synchronous buck control ICs with benchmark HEXFET® trench technology in a compact 5mm by 6mm Power QFN package, shrinking the silicon footprint by 70 percent compared to discrete solutions, and offering up to 10 percent higher full-load efficiency than competing monolithic ICs. The SupIRBuck IR38xx family of nine devices provides a highly efficient power solution for data center applications including enterprise servers while the SupIRBuck IR380x family of six devices for consumer embedded POL applications up to 14 amps are optimized for high performance consumer applications including game consoles, desktop PCs, graphics cards, set-top boxes and LCD TVs.

“We are delighted to receive this award from Electronic Products China. Featuring a high level of integration and small footprint, the SupIRBuck family of integrated voltage regulators delivers significant space savings while offering superior flexibility and efficiency over traditional solutions,” said Tim Phillips, vice president of IR’s Enterprise Power Business Unit.

Designed for 4, 7 and 12 amps of output load current, common features include wide range input of 2.5V to 21V and output range of 0.6V to 12V, pre-bias start up, fixed 600kHz switching frequency, hiccup current limit, thermal shutdown and precise output voltage regulation. Optional features include 300kHz switching frequency, tracking for DDR memory applications and programmable Power Good. SupIRBuck’s thermally enhanced package with slim 0.9mm profile, allows mounting on the back-side of the motherboard, making the devices ideally suited for space constrained, high-density applications.
