Sixteenth-Brick
DC-DC Converter
The PQ60050SMx10 PowerQor Mega sixteenth 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 not explicit thermal
interfaces, it is extremely reliable. RoHS compliant
(see page 15).
Operational Features
• High efficiency, 86% at full rated load current
• Delivers up to 50W of output power with minimal derating
• Operating input voltage range: 35-75V, 100V with 100ms input
transient capability
• Fixed frequency switching provides predictable EMI
• No minimum load requirement
