The QRW series provide up to 25A 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 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. * ISO is a registered trademark of the International Organization of Standards ** UL is a registered trademark of Underwriters Laboratories, Inc. † CSA is a registered trademark of Canadian Standards Association.

An input line fuse must always be used. This power module can be used in a wide variety of applications, ranging from simple stand-alone operation to an integrated part of a sophisticated power architecture. To preserve maximum flexibility, internal fusing is not included however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies require a normal-blow fuse with a maximum rating of 10 A see Safety Considerations section . Based on the information provided in this data sheet on inrush energy and maximum dc input current, the same type of fuse with a lower rating can be used. Refer to the fuse manufacturer’s data for further information. Lineage Power The temperature at any one of these locations should not exceed per Table 1 to ensure reliable operation of the power module. The output power of the module should not exceed the rated power for the module as listed in the Ordering Information table. Although the maximum Tref temperature of the power modules is per Table 1, you can limit these temperatures to a lower value for extremely high reliability.
