  • TPS74901: TPS74901: When input=3.3V and output 1.8V, how to configure Vbias?

    Resolved
    Part Number: TPS74901 Hi team, As we know that the VBias must be 1.75V above Vout. In this case, Vbias need at least > 3.35V(1.8V+1.75V = 3.35V). but the board doesn't have 5V source. Could we use resisters to divide 12V source to 5V for VBias? If…

  • TPS74901: Thermal Pad No Connect

    TI Thinks Resolved
    Part Number: TPS74901 Hello E2E, We are using TPS74901DRCR (VSON) in one of our designs. We have not connected thermal pad to ground and left it floating. Will it affect VR electrical operation, or only thermal performance? It seems from the datasheet…

  • RE: TPS74901: Transient_Response_&_O/P_Capacitor_Calculation

    Hi Dhanabal, TPS7A57 has a current source reference and an internal unity-gain LDO buffer, this allows to set Vout using the REF with a single resistor, compared to more traditional LDOs that use a voltage reference. The DAC53204RTER has a Current-Output…

  • TPS74901: Can Vbias connected to Vin at 2.5V?

    Resolved
    Part Number: TPS74901 Other Parts Discussed in Thread: TPS740 Hi, I am using the TPS74091 to generate 1.8V from 2.5V. Can I connect Vbias to the same 2.5V as Vin? Or it has to be 1.75V larger than 1.8V? Thank you.
