PSPICE for TI - TPS2662x - Fixed OVP

Pete5

Hi,

i am trying to simulate the ovp limit of the TPS2662, but it seems that even if i try and set it via the voltage divider the ovp is fixed at about 30V.

Here is my circuit for setting the ovp to 50V:


I also tried disabling the ovp and uvp:

But with both circuits the output voltage and output current is basically 0. But if i set the input voltage to 30V the circuit works. Did i do something wrong or is the simulation model wrong?

Thanks a lot!

    As per formula in the datasheet, it should work upto 50V as per the resistor values you have used.
    Might be some issue with the model.
    Better to post it on TI forum to report the same
