Hi Team,
LM5176 EVM test problem.
1. Vin12~13V to 12Vout will have high gate blanching, current about 5A.
2. Vin under 11V measures Q5 as shown in the figure. high-gate does not switch on . At this moment, Q5 will heat up and the voltage will flow from the body diode.
3. Vin 13 above measurement Q5 is shown as high-gate switch on.
Is this blanching normal phenomenon? How to improve? thanks
Sincerely
Kevin
Please let me know the results. It is really weird the EVM behaves that way.
Thanks,
Youhao

Hi Youhao,
Understand, I 'm still waiting for samples to test, and I have not yet received samples.
thanks
