Temperature rise is 55C in typical buck or boost circuits with the rated IDC 4. To determine copper losses, calculate: 2 current and reference ET applied to the inductor. Copper Loss (mW) = IDC x DCR 2. Total loss in the inductor is 80 mW (ROS 1) and 280 mW (ROS 2) for 55C 5. For core loss in mWatts, using frequency f (in Hz) and operating temperature rise above ambient. flux density B (in Gauss), calculate: 1.26 2.11 3. To estimate temperature rise in a given application, you must determine the Core Loss (mW) = k2 * f * B total losses (copper losses + core losses) and apply the following formula: 6. For flux density (B), calculate ET (V-sec) for the application, .833 Temp Rise (C) = (Total Losses (mW)) * KO (from table) and multiply by ET10 factor from the table.
