Die Temperature* : The temperature measurement was taken at the hottest point on the MIC26603-ZA while it was case mounted on a 5in² 4-layer,
0.62”, FR-4 PCB, with 2oz finish copper weight per layer. See the “Thermal Measurements” section for more details. Actual results will depend on the
size of the PCB, ambient temperature, and proximity to other heat emitting components.
