31DC-DC Converter Design and Magnetics

the worst-case stress it is going to endure in our application. And then, provided that that

particular stress parameter happens to be a rele

vant and decisive factor in its selection, we

usually add an additional amount of safety margin, for the sake of reliability. However,

the problem is that different stress parameters do not attain their worst-case values at the

same input voltage point. We therefore realize that the design of a wide-input converter is

necessarily going to be “ tricky. ” For sure, designing a functional switching converter may

be considered “ easy, ” but designing ...
