CHRK Cherokee International Corp (MM)

Cherokee International (NASDAQ:CHRK), a leading manufacturer of power supplies, today announced that it has received a patent for its innovative �Lossless Clamp� circuit for DC/DC converters that can be used as a standalone stage or incorporated in AC/DC products . The �Lossless Clamp� patent lowers dissipation losses and renders the DC/DC converter stage more efficient. �Based upon our experience, we have found that this patent has extended our performance for circuits using synchronous rectification by minimizing the drain to source voltage spike during switching transitions resulting in a significant gain in efficiency to the order of several percentage points,� said Michael Wagner, vice president of marketing for Cherokee International. �This effort was spearheaded by Moshe Domb, director of research and development for Cherokee International in collaboration with several other members of the engineering team including Jackie Tang, director of engineering and Alex Patel, vice president of engineering.� With Cherokee International�s now patented approach, overall power supply efficiency is improved by 3-4 percentage points � a key win in an industry where overall efficiency is a driver for OEM design wins. This patented approach is currently available in the company�s CAR2500 Series, CAR1200 Series, and several custom power supplies. �We are extremely excited about this patent and proud of our engineering team for its ability to improve efficiency performance within our products,� said Jeffrey M. Frank, president and CEO for Cherokee International. �The patent is particularly valuable and constructive as our customers continue to advocate higher system level efficiencies with the goal of increasing their competitiveness in their end markets while at the same time reducing their total cost of ownership.� About Cherokee International Cherokee International designs, manufactures and markets high-reliability custom and standard switch-mode power supplies for datacom, telecom, medical and process-control applications.
