**Part Number:**UCC28180

When dimensioning a PFC circuit based on UCC28180, we will use the excel tool from TI.

When calculating the technical parameters of the PFC choke, the maximum peak current IL_PEAK is 17.5A and the boost inductor value LBST is 0.130mH. How should this information be understood?

In the data sheets of PFC chokes, the inductance is often specified at a saturation current and a nominal current.

In this case, must a PFC choke be selected which has 0.13mH at saturation current (17.5A) or at the nominal value?

Or how should the PFC choke generally be selected?
