Optimize Low-Power Efficiency of Your Interleaved PFC
Energy efficiency requirements can provide the impetus for the design of innovative, less power-hungry power supplies for desktops and servers. Use interleaved two-phase power factor controls (IPFCs) in applications when strict form factors must be met like (i.e., slim notebook adapters or LCD TVs). Read this application note to learn how adjusting the frequency fold-back characteristics of IPFCs can optimize circuit efficiency across the load range.
