Buck regulator IC drives automotive gains

Santa Clara, Calif. – National Semiconductor says its LM5005, for easing industrial, automotive, and telecom designs, is the industry’s first 75-volt, 2.5-amp integrated buck regulator. “The LM5005 addresses our customers’ requests for a higher-current version of the popular 75-volt, 1-amp LM5010 and 75-volt, 500-mA LM5007 buck regulators,” said Paul Greenland, director of strategic marketing for the Power Management Group. “The entire family is highly integrated for a smaller overall footprint, with unique, high-frequency PWM control circuitry that allows our customers to implement step-down switching regulators with minimal filtering and external components.”
