Dear all As we known, the power consuming of IC in different temerature is different. If the enviroment temperature is from -40 to +85 centigrade, how much is the differenc between highest and lowest power consuming? Now I could get the power consuming in 25 centigrade. I want to get the limitation for the power module. Any advice would be helpful.
