Hi Satoshi,

We don't have UCC28180 controlled bridgeless PFC. The difficulty is the current sensing. A current shunt, no matter where you put in the bridgeless PFC, it does not sense the whole input current. However, we do have UCC28070 bridgeless solution, please check this link: www.ti.com/.../slua517.pdf
