IR3720 and IR3721 power monitor ICs are IEC 2009 DesignVision Awards’ finalists

IR3720 and IR3721 power monitor ICs from International Rectifier have been named finalists in the International Engineering Consortium’s (IEC) 2009 DesignVision Awards which recognize the design tools and products judged as the most unique and beneficial to the semiconductor industry.

The IR3720 (digital) and IR3721 (analog) output power monitor ICs for low-voltage DC-DC converters used in notebook, desktop computers, and energy-efficient server applications feature IR’s patent-pending TruePower technology to accurately capture highly dynamic power information to maximize system performance.

“The IEC is pleased to name International Rectifier’s IR372x family of ICs as one of the most beneficial contributions to the electronic design industry with a 2009 DesignVision Finalist designation," declared IEC President John Janowiak. "We encourage industry professionals to learn more of this impressive design solution at this year’s DesignCon 2009 exhibition and experience first-hand how to better deliver measurable results.”

The IR3720 and IR3721 ICs monitor the output filter inductor current in buck or multiphase converters from 0.5V to 1.8V and provide designers with the option of using resistive sensing or inductor DCR current sensing with an internal thermal compensation feature to achieve higher efficiency compared to existing solutions while reducing bill of materials and board size requirements.
