Thermal map
AN4027
In order to check the design reliability, a thermal mapping by means of an IR camera was
done. Below, the thermal measurements of the board, component side, at nominal input
voltage are shown. Some pointers, visible on the images, have been placed across key
components or components showing high temperature. The ambient temperature during
both measurements was 26 °C.
