Hello......

Can anyone say the difference between the PFC IC UCC28019AP & UCC28019P?

    The UCC28019AP is fully pin for pin compatible for designs using the UCC28019P.  Modifications were made to the "A" version of the device to reduce audible noise at start up by adding a pre-start current to Cvcomp and some modifications were made to the enhanced dynamic response immediately after soft start.  For applications that are sensitive to audible noise, the UCC28019AP device is recommended.
