The UC3845 is a current mode controller. You must consider the difference from the more usual voltage mode controller (UC3525). If a SPICE model exists, Texas Insturments will have it. Check their website (www.ti.com). Also look for application notes U110 and U111, these have info on transformer design and current mode design.
