TPS43061: Ripple noise on Output

Part Number: TPS43061

We recently spun some boards with the TPS4306 as one of our main supplies. With a 5V input, we boost to 12V at a frequency of 696kHz. We are noticing a fairly large ripple (~1V) when the LDRV is asserted high. We would like someone to review our layout and hopefully answer some questions around what the expected ripple would be. Unfortunately, due to confidentiality, I cannot post here, but if someone could reach out, that would be great!

  • Hi Luke,

    I have sent you a request through PMS system, and lets continue the discussion through email. I will close this thread here. Remember sending me your sch and key waveforms.

    Thanks,
    Youhao Xi, Applications Engineering.
