Temperature rise is 55°C in typical buck or boost circuits operating at 300 KHz with the rated Idc current and reference ET applied to the inductor. 2. Total loss in the inductor is 1.8 watts for 55°C temperature rise above ambient. 1.097 27,86 2 3 3 .400 10,16 .600 15,24 P059X Date Code Country of Origin 1 2 3. To estimate temperature rise in a given application, determine total losses (copper losses + core losses) and apply this formula: TempRise (C) = (Total Losses(W)).833 x 33.783 4. For copper losses, calculate: CopperLoss(mW) = Idc2 x DCR 5. For core loss, using frequency (f: hertz) and flux density 4 1 .155 3,94 (B: gauss): CoreLoss(mW) = 1.0769E-09 * f1.26 x B2.11 4 6. For flux density (B), calculate ET (V-µsec) for the application, and multiply by the ET100 factor from the table. SUGGESTED PAD LAYOUT 1.220 MAX 30,99 7.
