  • TPS54561-Q1: Transient Current Load Response

    Resolved
    Part Number: TPS54561-Q1 Tool/software: Hi, a quick one on the TPS54561-Q1. My load is a bit noisy and the current can bounce around by a delta of up to 2A in 200-500ms. The regulator handles this pretty well, but I still see a ripple response on the…
