PMP22650: PMP22650: VT-20163 Transformer and VI-20174A PFC coupled inductor

Mahmood Akbar

Part Number: PMP22650

Tool/software:

i quiet like the design approach here, but the issue i am facing is that where to buy the magnetic parts in this design. Front End PFC coupled inductor and DC DC Transformer for CLLC stage both are little specialized parts.

i have never used coupled inductors before for PFC. i have experience of interleaved multichannel PFCs using individual discrete inductors. will we get single sourced if we go to coupled inductor and CLLC transformer with some integrated leakage inductance. i am little worried too from sourcing point of view.

Hi Mahmood, we worked directly with the magnetics vendors to define optimized magnetics for this design to achieve high performance so I don't believe their will be alternative parts that will be a direct replacement with the exact performance. However, if sourcing is an issue, I recommend reaching out to your cyntec contact to discuss this. cyntec has been around for some time now. we use them a lot on our reference designs. thanks!
