TPS54622: a problem of power TPS54622

Part Number: TPS54622

Hello, everyone. There is a problem of power interference. However, it interferes with the operation of our products when plugging and unplugging other electronic products. Our product is 12V to 3.3V; 3.3V to 1.2V. The oscilloscope captured the 1.2V waveform


  • Hello,

    Did you provide the captured waveform? There are not much details to help conducting the investigation.
    Please provide not only the 1.2V waveform, but also the 3.3V and the 12 V waveform at the time of plugging/unplugging.
