  • TPS717: TPS717 Output voltage raise up during over current

    Resolved
    Part Number: TPS717 We test the TPS717 input voltage is 5V, and output is 1.8V. The output load transient is 0A to 400mA as like the system load. We find the output voltage raise up during over current. As I know the voltage should be drop down. May I…

  • TPS717: Recover from UVLO

    TI Thinks Resolved
    Part Number: TPS717 Hi Team, My customer plan to use TPS71701 in their one of app and they have a stuck issue now. When performing a test to toggle Vin as a stress test, Vout sometimes stays low even though Vin was back to 5V. According to TPS717 datasheet…

  • TPS717: Feedback Divider Impedance

    TI Thinks Resolved
    Part Number: TPS717 Page 18 of the TPS71701 data sheet indicates that the lower resistor of the feedback divider MUST be between 160k and 320k: In the application in question, we need to hit a fairly tight (3%) output regulation accuracy and need to…

  • TPS717: Check points for stability operation

    TI Thinks Resolved
    Part Number: TPS717 Hi Team, I have three questions about TPS717. Could you answer following questions? 1. Let me confirm if the Ifb value is typo or not. The I_FB max is 1uA so it might introduce 0.32V offset by 320kohm FB divider… 2. Is it possible…

  • TPS717: adjustable output voltage calculation

    TI Thinks Resolved
    Part Number: TPS717 HI Team, this does not look right section 8.2.1.2 :- the denominator will be negative?
