Lambda & Broadband TelCom Power announce licensing agreement

LAMBDA AND BROADBAND TELCOM POWER ANNOUNCE LICENSING AGREEMENT.

SAN DIEGO, CA (MAY 30, 2002) - Lambda, a leader in the design and manufacture of AC-DC and DC-DC power supplies, and Broadband TelCom Power (BTCP), an innovative leader in the design and manufacture of high current density DC-DC converters utilizing its patented Flat Matrix Transformer technology, have announced a licensing agreement on the 50A quarter brick DC-DC converters.

The agreement allows Lambda to market these leading edge products worldwide. Lambda will manufacture this series of high current quarter bricks in its highly automated Malaysian facilities.

"We are very excited about this series of products. Many users of high density DC-DC converters are reluctant to embrace leading edge technology due to the lack of viable second sources," said David Norton, director of marketing for Lambda. "With this agreement, we can provide a true alternative utilizing different factories and different supply chains and leverage Lambda's true global sales network."

"We are very pleased with this licensing agreement. BTCP has been a leader in bringing best-of-class DC-DC converters to the marketplace," said Kam Sihota, vice president of marketing for BTCP. " With this agreement, we can leverage the global distribution network of Lambda to accelerate the adoption of our leading edge, high current density products."

BTCP's innovative technology can provide 50A in the industry standard quarter brick footprint utilizing patented Flat Matrix Transformer technology. Conventional transformers utilize a single core with multiple windings to achieve a voltage step-down ratio, whereas Flat Matrix Transformer technology uses multiple cores with single or minimal windings. This technology is better suited to handle heat dissipation, thus allowing higher current density products.

This new, "best of class," quarter brick, answers the continued demand in the industrial and telecommunications markets for robust DC-DC converters with lower voltage and higher current requirements in an increasingly smaller footprint. Utilizing patented and patent pending technologies, this series offers a cost-efficient, open-frame synchronous rectification design capable of delivering output up to 50A at 1.8Vdc and 1.5Vdc, 45A at 2.5Vdc and 40A at 3.3Vdc, from a 48V nominal input with a range of 36Vdc to 75Vdc.

BTCP is an innovative technology leader in high performance power supplies, and its proprietary Flat Matrix Transformer technology redefines technology limits in current density and thermal management.
