pfc bcm (boundary current mode) method output 200 w 400 v (bd7693fj)

the bd7693fj-evk-001 reference board outputs 400v voltage from the input of 90vac to 264vac. the output current supplies up to 0.5a.the bd7693fj whict is bcm method pfc controller ic is used.

  • the bd7693fj supplies the system shich is suitable for all of products that requires pfc.
  • bcm is used for pfc part,and zero current detection reduces both switching loss and noise.
  • thd is less than 6%.
