  • TPS630242: current limiting and output instability

    Resolved
    Part Number: TPS630242 Other Parts Discussed in Thread: TPS63024 hello we use a current limiter (250ma) to charge a large cap (3mF) to 5v and then use the TPS630242 to make 3.3v out of it. we choose the buckboost so we can catch large current spikes /…
