LM25122-Q1: gate output

Jin-Suk Choi

Part Number: LM25122-Q1

Hi~

Customer is under development with LM25122-Q1 but there is some distortion in gate output.

When I check on EVM, EVM also has same gate output distortion(HO).

Would you explained why and can we improve? is there no side effect?

Thanks.

    You should monitor HO-SW, instead of HO itself. The driver output is actually HO-SW, and that should be solid and steady.
    SW may have switching ringing, which is normal in switch mode converters, and this makes HO appears ringing. I am not concerned.
