Part Number: LM74700-Q1

Hi team!
I have a question about the cabout receiving current more than 6A LM74700-Q1.
I have standart sch with Nch MOSFET NVMFS5C604NL Onsemi. Vin, Vout = 12V.
However, when current 6A is reached, I have no working state and large ripple
Help how to get current up to 20A
Best Regards, Alex

Hi

Can you please share a waveform showing the behavior after 6A current.

After 6A does the MOSFET turn ON/OFF? Please explain with details about the problem.

Regards,
Kari.
