    TI Thinks Resolved
    Part Number: TPS63031 Other Parts Discussed in Thread: TPS61031 Hi I am testing with the TPS63031 The circuits is as follows It is a circuit that receives power from a 3V coin battery and outputs 3.3V When measuring current consumption without applying…

  • TPS63031: [urgent] Need help to debug with output voltage

    Part Number: TPS63031 Hello I have a small board with TPS63031. I tried to get a 3,3v output with 5v input but not success. I’m afraid that En signal don’t suitable in this case. Here is original schematic and board design. I tried to remove all parts…

  • TPS63031: TPS63031 quiescent current issue

    TI Thinks Resolved
    Part Number: TPS63031 hi, My customer use TPS63031 to design a low-power system. The datasheet show its quiescent current is 35uA(max). But we have tested the Iq is more than 6 mA. Test the current through string the multimeter into the input. Could you…

  • TPS63031: High current consumption than shown in the quesient current colomn

    TI Thinks Resolved
    Part Number: TPS63031 Hi, I am using TPS63031 to power a 3.3Volt circuit from a Lithium ION battery of 3.7 Volt. The circuit is mostly in low power mode consuming 5uA current. When I tested the current consumption of TPS63031, it seems like 5 mA is being…
