Abstract :
A design procedure for a DC-to-DC converter is presented taking the properties of the required inductor type into account. It is applied to a miniaturized 1.4 MHz boost converter with a power range below 1 W using ultra thin printed circuit board integrated inductors. As a result, it is more efficient to operate in the continuous mode, if the used inductor type has an increased AC resistance. The losses could be reduced by 30% compared to a reference design.
