3) Specified RthJA value is according to Jedec JESD51-2,-7 at natural convection on FR4 2s2p board; The Product

(Chip+Package) was simulated on a 76.2 x 114.3 x 1.5 mm board with 2 inner copper layers (2 x 70µm Cu, 2 x 35µm Cu).

According to JESD51-5 a thermal via array under the exposed pad contacted the first inner copper layer. Ta=25°C, Power

Switch and freewheeling diode are dissipating 1W.
