Hi, TPS22920 5 pin is connected to TPS2559 EN pin The power-on sequence should be to turn on the current-limiting IC TPS2559 and turn off TPS22920. In this case, the model number should be TPS22920L (low voltage enable)?
Hello, thank you for your reply, it should be TPS22920, there is ABCD silk screen next to the IC. Thank you very much for your help!

Hello, thank you for your reply, pin 5 is connected to TPS2559 EN pin.
I'm learning circuit analysis and design but I can't get the information to find a component, do you know anything? Please tell me, thanks! 3.3V IN is the input terminal of current limiting IC (TI TPS2559).
