NOTES: 1. Temperature rise is 55°C in typical buck or boost circuits operating at 300kHz
with rated Idc current and reference ET applied to inductor.
2. Total inductor loss is 1.8W for 55°C temperature rise above ambient.
3. In high volt-time applications, additional heating in the component can occur due to core
losses in the inductor which may necessitate derating the current in order to limit the
temperature rise of the component. In order to determine the approximate total losses
(or temperature rise) for a given application, both copper and core losses should be taken into
account.
