  • RE: TPS548D22: TPS548D22 output voltage setting

    Resolved
    1) TPS548D22 has 2 way to set output voltage such as 8. Remote Sensing Without Feedback Resistors and Remote Sensing With Feedback Resistors. I would like to set Vout = 1V. Which way do you recommend? And why? In general, I would recommend setting the…

  • Question about TPS548D22 board to have more output flexibilities.

    Other Parts Discussed in Thread: TPS548D22EVM-784 I am having a question on this design, if there is a way to have a board with this chip that the output voltage and current are not set to the extreme, and can be adjusted to different values within the…

  • RE: TPS548B22: Switch frequency changed

    Hi Benjamin, It is possible that the device is operating in SKIP mode. Can you please check what is the load at this condition? Also, what is the output capacitance of this application. If Cout is too little, this could cause a lot of ripple at the…
