International Rectifier announced that its IR3720 and IR3721 power monitor ICs 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 TruePower technology to capture highly dynamic power information to maximize system performance.
The IR3720 and IR3721 ICs monitor the output filter inductor current in buck or multiphase converters from 0.5 V to 1.8 V, and reportedly 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.
