The maximum power dissipation is a function of TJmax, θJA, and TA. The maximum allowable power dissipation at any ambient
temperature is PD = (TJmax − TA)/θJA. If this dissipation is exceeded, the die temperature will rise above 125°C, and the LM2990 will
eventually go into thermal shutdown at a TJ of approximately 160°C. For the LM2990, the junction-to-ambient thermal resistance, is
53°C/W, 73°C/W for the DDPAK/TO-263, and the junction-to-case thermal resistance is 3°C. If the DD[AK/TO-263 package is used, the
thermal resistance can be reduced by increasing the P.C. 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.
