Hi,
I'm a FAE to support Samsung. My customer want to use LM338 for below condition.
Input : 24V, Output : 15V, 3A / Power dissipation : (24V-15V)*3A = 21W
I have some question.
Q1. Is it usual case for LM338 application? I think the power dissipation is too high.
Q2. I want to calculate junction temperature. Do I using that formula? Tj = Ta + (Theta(JA)*Pdiss)
