Hello TI
If you connect the Raspberry Pi 5V line to SW1 of the TPS54386, it turns off after 2-3 seconds.
The 12V supply is supplied by the power supply and is displayed on the power supply.
The current turns off when it reaches about 0.4~0.5.
If you supply 5V power directly to the Raspberry Pi 4 as a power supply, you can see that it uses about 0.4A~0.6A when booting.
