| Preliminary Product Brief * For Discussion with Tyco Electronics Customers Only - Tyco Electronics Proprietary Phone: 800-253-0490 Fax: 408-732-2002 www.xp-foresight.com QRW 40A single output series Industry standard Quarter brick DC/DC converter, 36Vdc-75Vdc (48V) input voltage range, Output voltages available from 12V-1.0V * * * * * Delivers up to 40A output current Ultra High Efficiency: 91% @ 3.3V full load Improved Thermal Performance: -1 25A at 70C at 1ms (200LFM) High power density: 100W/in Low output voltages down to 1V: supports migration to future IC and microprocessor supply voltages Active load sharing option: Paralleling Cost efficient open frame design Optional heat-sink: to permit operation over extended ambient temperature ranges * * I II III IV (approval pending) * The QRW-series dc-dc converters are a new generation of DC/DC power modules designed for optimum efficiency and power density. The QRW provides up to 40A output current in an industry standard quarter brick, which makes it an ideal choice for small space, high current and low voltage applications. The converter uses synchronous rectification technology and innovative packaging techniques to achieve ultra high efficiency reaching 91% at 3.3V full load. Thanks to the ultra high efficiency of this converter, the power dissipation is such that for most applications a heat sink is not required. In addition, the QRW-series supports future migration of semiconductor and microprocessor supply voltages down to 1.0V.
