6.8.3 Procedure

  1. First determine the maximum power dissipated by the buffer, PD(MAX). For the simple case of the buffer driving a resistive load, and assuming equal supplies, PD(MAX) is given by:
    Equation 7. PD(MAX) = IS (2V+) + V+2/4RL

    where

    • IS = quiescent supply current
  2. Determine the maximum allowable die temperature rise,
    Equation 8. TR(MAX) = TJ(MAX)-TA(MAX) = PD(MAX)θJA
  3. Using the calculated value of TR(MAX) and PD(MAX) the required value for junction to ambient thermal resistance can be found:
    Equation 9. θJA = TR(MAX)/PD(MAX)
  4. Finally, using this value for θJA choose the minimum value of copper area from Figure 6-4.
