Other Parts Discussed in Thread: TPS62180

Is there any experience to use the TPS62180 with a coupled Inductor like LPD5030 Series from Coilcraft?   What are the drawbacks/benefits?  Do you have an test report?

    There is nothing that generally prevents TPS62180 from running with coupled inductors. Though this haven't been tested yet.

    The following need to be taken into account:

    1) There might be no significant size advantage finally, because coupled inductors are not soo small.

    2) The routing might bee more complicated/challenging and might add routing area as well.

    3) The coupled inductors represent a hot spot compared with distributed ones.

    Regards
