Sixteenth-Brick
DC-DC Converter
The PQ60015SMx25 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 no explicit thermal
interfaces, it is extremely reliable. RoHS compliant
(see last page).
Operational Features
• High efficiency, 83% at full rated load current
• Delivers up to 37W of output power with minimal derating
• Operating input voltage range: 35-75Vdc, with 100V for 100ms input
transient capability
• Fixed frequency switching provides predictable EMI
• No minimum load requirement
