UCC28064A: PFC Power Rating

D R
Prodigy 70 points
Part Number: UCC28064A
Other Parts Discussed in Thread: UCC256404,

On the specs page I see that this device supports systems with power less than 150W. 
I planned to use this part with UCC256404 LLC controller, as suggested on the datasheet of the LLC controller. Output power will be 200W max, with 100W nominal Pout. Is this still doable. If not, can you suggest alternative PFC module for this application?

    Hello DR, 

    Thank you for your interest in the UCC28064A interleaved TM-PFC controller. 

    Yes, the UCC28064A will work in your application.  The product page "Features" listing indicates that the UCC28064A works best at maximum output power levels ranging from below 150W to above 750W.  It will also work at power levels beyond these "limits" but this controller choice becomes less feasible.  The interleaved topology becomes excessively complex and costly for Pout significantly < 150W, and the peak currents and component sizes become excessive for Pout significantly > 750W.   

    Since your LLC output can be 200W max, the PFC output power will be > 200W which is well within the reasonable range of application for this device.  

    Regards,
    Ulrich
