REFACDC042 - Reference Design

PFC BCM (Boundary Current Mode) Method , Output 200 W 400 V

The BD7695FJ-EVK-001 reference board outputs 400V voltage from the input of 90Vac to 264Vac. The output current supplies up to 0.5A. The BD7695FJ which is BCM method PFC controller IC is used.

  • The BD7695FJ supplies the system which 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 8%.
