Die Temperature* : The temperature measurement was taken at the hottest point on the MIC24056 case mounted on a 5 square inch 4 layer, 0.62 inch,
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.
