Hi all,

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)
