RE: UCC38050: UCC38050 PFC based SMPS - operation on 400Hz AC input
Hello Janos, Thank you for your interest in the
UCC38050
TM-PFC controller. To answer your last question first, there is no risk to operate the PFC on a DC input. It will simply act as a boost regulator and the input current waveshape should track...
