  • Hi Jeffrey,

    The schematic looks good. Only one comment from my side.

    I notice our customer is using a bead BLM18AG102SH1D on both input and output side of our TPS62170-Q1. Usually we don't add this. Also the impendence of the bead is too large at switching frequency 2.25MHz(~100Ohm) which means the inductance is ~7uH. I think there's no need to add this bead since there's already an LDO after the output.

    If our customer must add this bead, please have a full test of the system to ensure the performance.

  • Hi Athos,

    Thanks for your support. As I checked with the customer, they accepted and will apply your guide on their circuit.
