Above 500KHz switching power supply

LIBIN VADAVATHI
Prodigy 60 points
Other Parts Discussed in Thread: LM5021

Could you please advise me on below technical query.

I have to design a 16.2W(12V-1.3Amps &6V -0.1Amps) isolated power supply with input supply of (100-460)V AC 60Hz.

And the main requirement is switching frequency should be more than 500KHz, since it is used for power line communication.

Please suggest  any  TI device for above application and which topology is comparatively simple(in design point of view) and better for this requirements. 

It would be much appreciated if you could send reply as soon as possible.

 

Best Regards,

    Libin,

    Please take a look at LM5021, this part configured in a flyback will work for this power level and switching frequency.

    Thanks,
