International Rectifier's DC/DC Power Managment Portfolio Grows with the Acquisition of Unisem

International Rectifier (IR, El Segundo, CA) has expanded its engineering capabilities and dc/dc power management integrated circuit (IC) product lines with the acquisition of Unisem Inc., completed on January 5, 2001.

Among the new products IR acquired with Unisem are switching control ICs and LDO regulators, which the company claims meet or exceed voltage and power requirements recommended by major microprocessor manufacturers for desktop, notebook and mobile applications. IR's array of LDO regulators also expanded to include a single-die, dual regulator device (the IRU1260), as well as low- and very-low dropout regulators.

The devices are offered in a wide selection of industry-standard packages as well as the UltraThin-Pak, a low-profile, single in-line package, and the power SO-8, which the company claims has three times more power dissipation than the standard SO-8 package.

Walt Lifsey, vice president of corporate development, commented, “International Rectifier's corporate mission is to deliver the most efficient and cost-effective power management components and systems in the world. Our expanded portfolio of dc/dc technology allows us to offer customers value-added power management solutions for the world's most demanding and rewarding applications. With our complete solutions, customers get to market faster with more competitive products."
