Hi,

do we have a part similar to this that can take an input up to 550V and can be paralleled to do a 3ph system?

Thank you!

Hi Alberto,

Unfortunately there is no analog 3 phase buck PFC controller within TI. There is some precedence for implementing analog PFC controllers on each of the phases, feed each PFC output to its own isolated DC/DC block and then have load sharing between the 3 isolated DC/DC's. This article has further references for using this approach:www.eetimes.com/document.asp
