Sep 29, 2011 | Technology Media

EL SEGUNDO, Calif. — International Rectifier, IR® (NYSE: IRF), a world leader in power management technology, today announced it has been named a winner in the annual Top-10 DC-DC Power Product Awards, hosted by Electronic Products China (EPC) for its scalable easy-to-use, versatile SupIRBuck® family of integrated point-of-load (POL) voltage regulators for energy-efficient consumer DC-DC applications including printers, LCD TVs, and game consoles.

The IR347x and IR386x SupIRBuck devices feature hysteretic constant on-time (COT) modulators with adaptive dead-time control to achieve superior light load and full load efficiency. The IR347x and IR386x, which integrate a high performance controller with optimized power MOSFETs in a slim 4x5mm or 5x6mm PQFN package, are designed with a 0.5 V, 1% accurate internal reference voltage, allowing very low and precise output voltage programmability. The devices offer a rich set of features including over-temperature protection, thermally compensated over-current protection, over and under voltage protection, pre-bias start-up power good output, and enable input with voltage monitoring capability.

"As with all of the members of the SupIRBuck family the IR347x and IR386x feature IR's latest advances in control IC, MOSFET and package integration technologies, and provide customers an easy-to-use and fully integrated DC-DC voltage regulator designed to deliver maximum efficiency. We are delighted to be recognized by Electronic Products China for our innovative DC-DC solutions," said Adam White, IR's Senior Vice President, Worldwide Sales.

The IR347x family is capable of up to 27 V input voltage and available in a 4x5mm and 5x6mm PQFN package to cover a broad range of loads from 6 A to 15 A, making it easily scalable to meet optimal price and performance requirements. These options and excellent light load efficiency make the IR347x an ideal choice for power conversion in mobile applications such as laptop computers. Other applications for the IR347x family include light industrial and battery-based applications that operate from 24V rails.

The IR3863 and IR3865, available in a 4x5mm PQFN package, are optimized for 12 V input applications and are well suited to consumer DC-DC applications including printers, LCD TVs, and game consoles.
