Tool/software:
Hi Team,
My customer is KOSTAL.
They are consulting the thermal calculation process of LM61460-Q1. Their calculation results show that the period temperature is 157℃ under the following working conditions, which exceeds the application conditions. Can you analyze how to calculate accurately?
The calculation process is as follows:
VIN=9~16V
Vout=5V
Iout=4A
Tamb=85℃
Fsw=400kHZ

According to Webench,IC Pd==1.06W
KSOTAL takes a smaller value and imports it into the thermal simulation software as follows:
The results are as follows:
