The QBK033A0B series operate off an input voltage range from 36 to 60Vdc and provide up to 33A output current at 12V in an industry standard quarter brick. The converter incorporates synchronous rectification technology and innovative packaging techniques to achieve efficiency reaching 94.5% at 12V full load. This leads to lower power dissipations such that for many applications a heat sink is not required. The output is fully isolated from the input, allowing versatile polarity configurations and grounding connections. Builtin filtering for both input and output minimizes the need for external filtering.

These are absolute stress ratings only, functional operation of the device is not implied at these or any other conditions in excess of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect device reliability.

An input line fuse must always be used. This power module can be used in a wide variety of applications, ranging from simple standalone operation to an integrated part of 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 fast-acting fuse with a maximum rating of 30 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 sheet for further information.
