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 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. • Delivers up to 40A output current • Ultra High Efficiency: 91% @ 3.3V full load • Improved Thermal Performance: -1 25A at 70°C at 1ms (200LFM) • High power density: 100W/in³ • 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 Specification • • • • • • • • • • • Tightly regulated output, typical ±1% Monotonic start-up into pre-biased output Output voltage adjustment trim +10% / -20% Load regulation ± 0.2% Line regulation ± 0.2% No minimum load required Ripple and noise (5Hz to 20MHz bandwidth) – RMS 40mVrms (3.3V) – Peak to peak 150mVpk-pk (3.3V) Operating temperature range: -40°C to 110°C Designed to meet basic insulation 1500Vdc isolation voltage Remote output voltage sensing Protection • • • Applications • • • • I) II) III) IV) Wireless Networks Access and Optical Network Equipment Enterprise Networks Latest generation ICs (DSP, FPGA, ASIC) and Microprocessor powered applications Output overcurrent and overvoltage protection Over-temperature protection Input under voltage protection Options • • • • • Positive remote on/off logic Active load sharing (Paralleling) Case ground pin Auto restart after fault shutdown Heatsink This product is intended for integration into end-use equipment.
