Hi. I'm new here. Recently I doing a photovoltaic system project. I found out uc2906 is quite a good ic for sealed lead acid charging ic. However, after I calculated all components values needed. I found out Multisim 11, Proteus Professional 8 and LTspice did not have the spice model for uc2906. The Texas Instruments library also does not have it. It is important to do simulation before proceed to hardware. I really need to find the spice model for it as I don't have much time left. Your helps will very appreciated. Thx.
