Thermal map
In order to check the design reliability, a thermal mapping by means of an IR camera was
done.
nominal input voltage. Some pointers visible on the pictures have been placed across key
components or components showing high temperature. The ambient temperature during
both measurements was 27 °C.
All other components of the board are working within the temperature limits, assuring a
reliable long-term operation of the power supply.
