Hello,

My schematic review of BQ25792 is as follows:

1. We recommend 3x pieces of 10uF and 1x piece of 0.1 uF on PMID.

2. What is the PROG pin connected to? Please follow table 9-1 in the BQ25792 datasheet for 1s configuration and proper switching frequency with inductor.

3. We recommend 5x pieces of 10uF and 1x piece of 0.1 uF on SYS.

I will turn it over to my PD counterpart to review the TPS25750.

Regards,

Mike Emanuel
