The acquisition will expand IR's technology by adding a leading digital power management platform that improves energy efficiency in a wide variety of applications, including computing systems, graphics, servers and gaming.

CHiL uses patented digital techniques in combination with mixed signal technology to deliver high performance multi-phase power solutions that save energy. The open architecture approach to digital control, where customers can tailor power systems for cost and performance goals, enables significant board space and bill-of-materials reduction, integrating many analog features into the digital core of the technology.

"The addition of CHiL's technology and expertise to our broad portfolio of industry leading products such as DirectFET, PowIRstage and SupIRBuck, offers IR's customers a unique value proposition by providing a high performance, cost effective, complete end-to-end integrated solution," said Tim Phillips, Vice President and General Manager, Enterprise Power Business Unit of IR. "Digital power management is entering a rapid adoption phase and the addition of CHiL's technology strengthens IR's market position to capitalize on this growth opportunity.

"The increased focus on energy efficient products over the next decade is expected to drive an expanding use of digital power management in applications such as DC-DC converters, AC-DC converters, lighting, inverters and Class-D audio systems," said Vishwas Karve, Vice President, Strategy and Business Development of IR. "The acquisition of CHiL expands IR's presence immediately in the high performance computing and graphics segments, over the medium-term in the server, storage and notebook end markets and longer-term across the Company's other vertical end market segments including Energy-Savings Products, Automotive Products and HiRel business units."
