UniFET—optimised switch for discontinuous current mode power factor correction

Posted: 03 Nov 2009     Print Version  Bookmark and Share

Keywords:power MOSFET  current mode  power factor correction 

This application note discusses merits of planar technology power MOSFET in discontinuous current mode power factor correction application. In most test conditions, it is cost-competitive and gives performance benefits compared with a super-junction technology device. The benefits are verified through the mathematical simulation and system-level experiments. A planar technology power MOSFET from Fairchild shows faster switching characteristics that contribute to higher efficiency and lower device temperature.
