TIDA-00779: Components not matching

Nidheesh BR

Part Number: TIDA-00779
Other Parts Discussed in Thread: UCC28180

In this design there are some conflicts.The capacitance values of C10 and C14 are mentioned in the schematic and the part numbers given are not matching.

why this?

In this case which value I have to choose?

Also the inductance value of L4 is not mentioned.What will be the ratings of L4?

Hi Jason,

I got your response. So as per your replay I understood that the L4 inductor is only for emi testing purpose. If I don't want to do emi testing I can short that with jumper and work the circuit as normal charger right.

Thanks.
