    TI Thinks Resolved
    Part Number: TPS62912 Other Parts Discussed in Thread: TPS62913 Hello TI support, I am thinking to use TPS62912 to get an precise supply voltage. I see from the data sheet that two LC filters would offer good ripple free DC. In my case I will have two…

  • TPS62912: Load switching and output transient voltage analysis

    TI Thinks Resolved
    Part Number: TPS62912 How can I perform load switching measurements on this part? For example: set the load/output current to draw 0.5A for 5ms and then to draw 5A after that? With the expectation to see voltage bounce on the output.
