Hi Team,
My customer using this part in his project and he found some issue need your clarify.
He mentioned that LM33620 block diagram show the AGEN and PGND is the some GND inside.
But they test PGND to AGND resistor value have M ohm. It seems not be the some like the datasheet said.
Because they find this issue from his soldering by hand the LMR33620 cannot startup , but he using the hot air gun to soldering again the LMR33620 will do.
The issue seems come from the AGND not really connect enough to happen.
Does the AGND not just the stronger thermal capability pad for LMR33620 ? Or it has the other function in here so must to connect.
