DC-DC Converter
The PQ60033EGx20 PowerQor® Giga eighth-brick
converter is a 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. All of the power and control
components are mounted to the multi-layer PCB
substrate with high-yield surface mount technology.
Since the PowerQor converter has no explicit thermal
interfaces, it is extremely reliable. RoHS compliant
(see page 12).
