DC/DC Converter URF1D HB-150W Series MORNSUN' Element model EMC solution-recommended circuit PCB layout 4. Thermal design The maximum operating temperature of base- plate TB is 100 C, as long as the user's thermal system keeps TB <100 C, the converter can deliver its full rated power. A power derating curve can be calculated for any heatsink that is attached to the base-plate of the converter. It is only necessary to determine the thermal resistance, Rth(B-A), of the chosen heatsink between the base-plate and the ambient air for a given airflow rate. This information is usually available...
