To determine copper losses, calculate: 1. Temperature rise is 55C in typical buck or boost circuits with the rated IDC current 2 Copper Loss (mW) = IDC x DCR and reference ET applied to the inductor. 5. For core loss in mWatts, using frequency f (in Hz) and operating flux 2. Total loss in the inductor is 80 mW (ROS1) and 280 mW (ROS 2) for 55C temperature density B (in Gauss), calculate: rise above ambient. 1.26 2.11 Copper Loss (mW) = K2 * f * B 3. To estimate temperature rise in a given application, you must determine the total 6. For flux density (B), calculate ET (V-sec) for the application, and multiply losses (copper losses + core losses) and apply the following formula: .833 by ET10 factor from the table.
