Note (2): Still air, low effective thermal conductivity board per JESD51-3.

Note (3): QFN bottom pad is recommended to be connected to ground.

Note (4): QFN θJ-A under 50% and 0% bottom pad soldered condition is 43°C/W and 72°C/W respectively. The data

was based on simulation results using a 4 Layer, 76.2 x 114.3 mm
