REFACDC037 - Reference Design
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%.
