I am currently studying on an embedded system design course, and working on a project using a MSP430 to control a LM2575-ADJ.
I would like to test the initial DC-DC circuit in OrCad but the trouble is I cannot find a Pspice model for the LM2575, I have tried both the National Semiconductor and Texas libraries. I have also looked at the datasheet for the DC-DC and there is no Psice data I can find.
Anyone have any idea's how to proceed as can build the circuit, but will save design time by simulating first?
(I am fairly new to OrCad but can work my way around the simulation and circuit design interface ok)
If you did not find the Spice models that you are looking for then you can always try the design software from TI, it is available for free download.
There is the Switchers Made Simple and PowerStage-Designer.

Thanks for the links I am sure these will prove useful.
