1 / 2 page Preliminary Product Brief * For Discussion with Tyco Electronics Customers Only – Tyco Electronics Proprietary I) This product is intended for integration into end-use equipment. All the required procedures for CE marking of end-use equipment should be fol lowed. II) CSA is a registered trademark of Canadian Standards Association. III) UL is a registered trademark of Underwriters Laboratories, Inc. IV) VDE is a trademark of Verband Deutcher Elektrotechniker e.V. (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.
