Evaluation Board Performance
Die Temperature* : The temperature measurement was taken at the hottest point on the MIC26903 case mounted on a 5 square inch 4 layer, 0.62”,
FR-4 PCB with 2oz finish copper weight per layer, see Thermal Measurement section. Actual results will depend upon the size of the PCB, ambient
temperature and proximity to other heat emitting components.
