Figure 6: Efficiency vs. Output Current

power from the input power.

= 14W – 13.2W ≈ 0.8W

With the power dissipation known, the temperature rise in the device may be estimated based on the theta JA

ΔT ≈ 0.8W x 12.5°C/W ≈ 10°C

temperature. We assume the initial ambient temperature to be 25°C.

≈ 125°C – 10°C ≈ 115°C

The maximum ambient temperature the device can reach is 115°C given the input and output conditions. Note

that the efficiency will be slightly lower at higher temperatures and this calculation is an estimate.
