Note 3: Please refer to “ Layout Recommendation”, the Thermal-Pad on the bottom of the IC should soldered directly to the PCB’s

Thermal-Pad area that with several thermal vias connect to the ground plan, and the PCB is a 2-layer, 5-inch square area with

2oz copper thickness.

Note 4: The case temperature is measured at the center of the Thermal-Pad on the underside of the TQFN5X5-32A package.
