Hi expert,

Customer is looking for a power solution that the condition is 45Vac/60Vdc input to 12Vo/200W.

They would use it for power over coaxial application like Set Top Box with 60Hz signal.

Would you please recommend a solution and/or a reference design?

Thanks,

Allan

Hi Allen,

This looks like something the SR team might have a better recommendation for. Here is a first pass from WEBENCH.

I hope this helps.

Hi JCHK,

I thought it might be something like high voltage controller? Do we have any similar and verified reference design can share?

Thanks,

Allan

Hi Allan,

You can do this with a general-purpose PWM controller like the UCC28C5x series. Just not sure that this is the optimal solution given the low input voltage.

I hope this can work for you.
