I would like to use LMZM33603 for Inverting buck-boost (IBB) topology.
Then, I understand that I can connect PGND pin and AGND pin.
Because, the device has AGND and PGND are internally tied in this device.
Please refer to the following E2E thread.
Is my understanding correct?
And, could you please let us know if you have any concern?
By the way, according to datasheet, “Do not connect this pin to PGND”.
This comment is advice for normal operation(buck topology).
Therefore, I understand that it is not applicable in IBB topology.
