The PQ60018ETL45 PowerQor Tera 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 14).
