DC-DC Converter  
The BusQor® BQ55090QTA27 bus converter is a next-  
generation, board-mountable, isolated, fixed switching  
frequencydc/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. The BusQor series provides an isolated step down  
voltage from 48V to 12 or 9.6V intermediate bus with no  
regulation in a standard “quarter-brick” module. BusQor  
converters are ideal for creating the mid-bus voltage required  
to drive point-of-load (non-isolated) converters in intermediate  
bus architectures.
