7.2.2.2 Thermal Dissipation

Junction temperature is determined using the junction-to-ambient thermal resistance (RθJA) and the total power dissipation (PD). Use Equation 6 to calculate the power dissipation. Multiply PD by RθJA as Equation 7 shows and add the ambient temperature (TA) to calculate the junction temperature (TJ).

Equation 6. PD = (IGND+ IOUT) × (VIN – VOUT)
Equation 7. TJ = RθJA × PD + TA

Calculate the maximum ambient temperature as Equation 8 shows if the (TJ(MAX)) value does not exceed 125°C. Equation 9 calculates the maximum ambient temperature with a value of 99.95°C.

Equation 8. TA(MAX) = TJ(MAX) – RθJA × PD
Equation 9. TA(MAX) = 125°C – 100.2°C/W × (4.3V – 3.3V) × (0.25A) = 99.95°C
