1400 PROVIDENCE HIGHWAY • BUILDING 2 NORWOOD, MASSACHUSETTS 02062-5015 WWW.INTRONICS.COM W7 SERIES DC/DC MODULES Applications • Servers, Switches and Data Storage • Wireless Communications • Distributed Power Architecture • Semiconductor Test Equipment • Networking Gear • Data Communications • Telecommunications • Industrial / Medical The W7 Family of high efficiency DC/DC converters offer power levels of up to 7 Watt, which exceeds that of other sub-bricks with the same package, while also providing Surface Mount Processable construction. With a wide input voltage range and single and multi-outputs, these converters provide versatility without sacrificing the board space. All models feature an input filter, continuous short circuit protection and regulated outputs. The fully enclosed, encapsulated construction facilitates maximum power delivered with the highest efficiency of up to 83%. All converters combine creative design practices with highly derated power devices to achieve very high reliability, high performance and low cost solution to systems designers.
