International Rectifier ( IRF) introduced the IRDC2086-330W, a reference design featuring the IR2086S DC Bus Converter control IC and DirectFET(r) power MOSFET chipset. The IRDC2086-330W is a 48V to 9.6V (35A) unregulated DC bus converter which has 97% efficiency and is 30% smaller than industry-standard quarter brick regulators. The reference design simplifies development of 48V input brick or embedded power supplies for networking, communications and high-end server applications. The IRDC2086-330W DC bus converter reference design is available immediately for $250 each. Prices are subject to change the company said. "IR's high voltage IC technology used in the IR2086S control IC works with the superb DirectFET MOSFET packaging technology reduces primary temperature as much as 40 degrees Celsius than standard solutions for increased system reliability," said Stephen Oliver, marketing manager for SMPS Products at International Rectifier.
