Hi Deepak,
I believe Danilo posted the same question in another E2E thread. I've assigned this to our PFC expert, but I will pre-empt by asking about the probing methodology:
1. Where exactly is this being probed? I assume this is the gate to ground…
Hi Danilo,
I've assigned this post to our PFC expert. However, he will ask the same questions, so I will post them here:
1. Where exactly is this being probed? I assume this is the gate to ground, but is it at the MOSFET or at the controller or somewhere…

Hi TI team,
I also put the 5.5Vout first and power on the device with 5V. The fault pin is triggered but It was not a normal protection mechanism, we still need you to clarify.
You can check the same question from TI E2E blog as below link.

Hi Dhinesh,
I can spin it with your json file now. Some tips here:
1. need to set the power to 24v
2. need to disconnect the USB before power 24v on and re-connect the USB
Hi Sho,
Those peripherals should not be contributing to the high power consumption.
A few things to consider for low power optimization:
In order for the MSPM0L1228 to enter STANDBY1, VBAT must be powered.
Only necessary jumpers on J101 should…
Hi,
BQ25887 does not have power path feature. Please try BQ25882 or BQ25883.
