Temperature Derating
The 1 Watt Output SLC series can be operated up to a +85°C
case temperature. Case temperature can be roughly calculated
from ambient by knowing that the case temperature rise is
approximately 58°C per package watt dissipated.
For example: If a 5S12.080SLC is delivering 0.9 watts at 5V
input, at what ambient could it expect to run with no additional
cooling such as moving air?
Efficiency is approximately 73% which leads to an input
power of 1.23 watts. The internal power loss is 1.23 - .9 = 0.33
watts. The case temperature rise will be 0.33W x 58°C/
W=19.1°C. This number is subtracted from the maximum
case temperature rating of 85°C to get 65.9°C, which is the
maximum ambient operating temperature.
This example calculation is for an application with no extra
air flow for cooling. Extra cooling air will greatly effect the
maximum ambient temperature. Exact internal power loss
depends upon the efficiency, input voltage, and load in the
application.
The above example is a rough approximation to the
maximum ambient temperature. Because of the difficulty of
defining ambient temperature, these calculations should be
verified by actual measurement before committing to a
production design.
