If the DDPAK/TO-263 package is used, the thermal resistance can be reduced by increasing the PC board copper area thermally
connected to the package: Using 0.5 square inches of copper area,
θJA is 50°C/W; with 1 square inch of copper area, θJA is 37°C/W;
and with 1.6 or more square inches of copper area,
θJA is 32°C/W.
