1. Temperature rise is 55° C in typical buck or boost circuits with the rated I
DC
current and reference ET applied to the inductor.
2. Total loss in the inductor is 80 mWatts (ROS 1) and 280 mWatts (ROS 2)
for 55°C temperature rise above ambient.
3. To estimate temperature rise in a given application, you must determine the
total losses (copper losses + core losses) and apply the following formula:
ROS 1:
TempRise (C) = (Total Losses (mW))
.833
x 1.45
ROS 2:
TempRise (C) = (Total Losses (mW))
.833
x .508
4. To determine copper losses, calculate:
CopperLoss (mW) = I
DC
2
x DCR
5. For core loss in mWatts, using frequency f (in Hz) and operating
flux density B (in Gauss), calculate:
ROS 1: CopperLoss (mW) = .127 x 10
-10
x f
1.26
x B
2.11
ROS 2: CopperLoss (mW) = .887 x 10
-10
x f
1.26
x B
2.11
6. For flux density (B), calculate ET (V-μsec) for the application,
and multiply by ET
10
factor from the table.
