DC-DC Bus Converters
    Single board construction for higher reliability
Bus Converters The BusQor® bus converter are the next-generation, board-mountable, isolated, fixed switching frequency DC-DC converters that use synchronous rectification to achieve extremely high conversion efficiency.  SynQor designs several manufacturing lines to comply with military standards and industrial needs.  The high-reliability DC-DC converters bring SynQor's field proven high-efficiency synchronous rectifier technology to the Military/Aerospace industry.  SynQor's innovative QorSeal packaging approach ensures survivability in the most hostile environments.  The MCOTS series provides an isolated step down voltage from 270V to 31V intermediate bus with no regulation in a standard half-brick module.  The Industrial line comes in Un-regulated, Semi-regulated and Fully-regulated models.  The SynQor bus converters are ideal for creating the mid-bus voltage required to drive standard point-of-load (non-isolated) DC-DC isolated converters.
