BusQor DC/DC Bus Converters
    Open-frame, single board construction for higher reliability
BusQor Series Bus Converters The BusQor® bus converter are the next-generation, board-mountable, isolated, fixed switching frequency DC/DC converter that uses synchronous rectification to achieve extremely high conversion efficiency. The power dissipated by the converter is so low that a heatsink is not required, which saves cost, weight, height, and application effort. BusQor converters are ideal for creating the mid-bus voltage required to drive point-of-load (non-isolated) converters in IBA.
