AN833 APPLICATION NOTE

eg. designing a 100kHz minimum fsw with a modulation depth » 20%:

fIn this way the advantage, in terms of reduction of the peak of energy in the noise spectrum, is remarkable. On

the other hand the increase of switching losses can be neglected because the maximum frequency occurs at

the minimum line current.
