400W HB LLC+PFC combo IC

MarkAmores — Wed, 21 Jan 2026 07:45:24 GMT

Good day!
I'm planning to start my AC-DC 375W (12V/24V) battery charger project. My current plan is to design AC-DC 400Wmax then use Buck-Boost DC-DC to accommodate the 12V and 24V mode.
May I ask for your expertise on which controller IC I can check to use on my AC-DC application?
HB LL+PFC combo IC is preferable for me as it lessens the component quantity and will be simpler to layout compare to multiple ICs.
Thank you for the suggestions!

Hello Guowei Sun,
Thank you for your suggestion. Can I still use this IC directly from supplier with the default values (as I checked it's a Digital configurable LLC) or do I really need to download and configure it on GUI to properly use it?

Regards,
Mark

For this part you can use it with or without GUI configuration.
