Description  
The 0RQB-F5S11x is isolated DC/DC converter that operates from a nominal 50V source. This converter is  
intended to provide isolation and step down to generate a regulated intermediate bus for the purpose of powering  
non-isolated Point-of-Load (POL) converters. This unit will provide up to 550W of output power from a nominal  
50V input. The output of the converter has the droop function which allow the modules operating in parallel with  
high output current sharing precision. This converter is provided in a 1/4 brick package.

CAUTION: This converter is not internally fused. An input line fuse must be used in application. Recommend a  
fast-acting fuse with maximum rating of 25 A on system board. Refer to the fuse manufacture’s  
datasheet for further information.  
Note: All specifications are typical at 25 C unless otherwise stated.
