PFC Controller for 2kW

[Zainul_Abideen]

Hi, 

I'm looking for a PFC controller for 2kW output, 

Input - 90-265VAC

Output - 400VDC

which controller IC do you suggest for boost topology with the least BOM count?

Hi,

depends at first: which mode you want : CCM or DCM ?

I use NCP1654 , ccm; and UCC38051 , dcm.

But the big problem is : to decide, which device can switch this power; and how to build the coil .
