TLV62568A: Power Management Circuit

Samiksha Hiranandani

Part Number: TLV62568A

I used the WEBENCH designer to design a circuit for converting an input voltage of 3.3V to 2.5V. I tried simulating the following circuit generated by the WEBENCH tool on PSpice but get an output of 3.3uV instead of 2.5V when applying an input voltage of 3.3V.

    Hello Samiksha,

    Thank you for your question.

    The schematic looks fine to me.

    Which simulation parameters are you using?

    I would suggest you to perform a transient simulation and to use pulsed voltage sources (starting from 0) instead of DC ones, to ease the simulation convergence.

    For reference please look at this simple schematic (simulated with PSpice for TI).

    Please ask again if you have any more questions.

    Thanks,

    Stefano
