I would recommend a generic controller like the UCC28c43 in flyback mode.

Hi Peng,

Can you tell me more about the application ? Is it for a LED driver for example, does it require isolation ?

What is the specification for the load share performance between the SMPS, how many are there in parallel ? TI has the UCC39002 load share controller which is a dedicated controller to force parallel power supplies to share the load current evenly.

Regards

Peter

Hi,Peter

Thanks for your reply.It is used for charging a lot of capacitors and suppling for some IC.It requires isolation.
