DC/DC Converter URF1D_HB-150W Series Element model Recommended value Choose according to actual input current EMC solution-recommended circuit PCB layout 4. Thermal design The maximum operating temperature of base- plate TB is 100 ℃, as long as the user's thermal system keeps TB <100 ℃, 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...
