Waytronx, the San Diego-based provider of openly licensable advanced systems cooling solutions, has acquired CUI, the Tualatin, Ore.-based provider of electronic components including power supplies, transformers, converters, connectors and...
Understanding that maximum device power is situation
dependent can go a long way in explaining why semiconductor
data-sheet specifications for power can be misleading
In a previous column, I tried to predict future trends in on-board power distribution, and the handling and distribution of input power to the various IC devices on the pc board. As each one of the devices keeps increasing in capability and...
Many device data sheets now list both of these thermal characterization parameters, but to apply them accurately in power-supply designs, engineers must understand the subtle differences in how these terms are defined.
By dividing PCB layers into arrays of small cells and calculating the thermal conductivity of each cell, a thermal simulation tool generates a more accurate thermal profile and accounts for local concentrations of copper on the board.
