Integrated Magnetics versus Conventional Power Filtering

Relative merits of the conventional low-pass power filtering methods in switched-mode power conversion are compared against the integrated magnetics technique. Both theoretical results and several practical design examples clearly illustrate that low profile, high power density switching dc-to-dc converters (in excess of 20W/cubic inch) for telecommunication applications are possible even employing moderate switching frequencies in 500kHz range provided an integrated magnetics technique is implemented.
