    Hello Eggsy,
    The UCC2818 and UCC3818 are 16 pin CCM pfc controllers
    The UCC3818 has a temp range of 0C to +70C
    The UCC2818 has a temp range of -40C to +85C
    The UCC28180 is a newer generation 8 pin CCM pfc controller. It has advanced features such as enhanced dynamic response, soft over current, no requirement for line sensing and a reduced current sense threshold.
    Most newer designs will use the UCC28180.
    There is a host of product design information and reference designs available at this web page:
