Simulation of LMZ31707

Hi,

I am simulating LMZ31707 for 3.3V output voltage. But it's showing output in the range on mV. 

I am attaching the screenshot for my schematic.

Regards,

Sumama Hashir

HI,

Ready to use LMZ31707 transient model circuit is avaialble in PSpice for TI. You can so download it from the tool itself from Part search UI and tune it as per your output voltage requirement. For 3.3 output voltage requirement, R3= 316 ohm and R2= 90.9k

.

Although you can build your own design, but from your schematic snapshot R2 and R3 values are not clear.

It would be good if you share your design so that it can be debuged.
