Note 1: The temperature measurement was taken at the hottest point on the MIC24051 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 emit-
ting components.
