Optimization is not solving with the input Capacitor, TOPSwitch/TinySwitch-II and/or Transformer that I wish to use. How can I work around this problem?
If the output power is beyond the capability of the device in question, the Optimization tool will choose the device combination which best suits your requirements. This choice is dependent on Optimization Parameters section within the Active Design on the main menu. If Optimization chooses a device, which is smaller than the preferred device, the user may force the preferred component choice(s). Simply select the desired device from the PI device selection dialog and then from the solutions filter dialog make sure that the core start entry and the core end entry is the same and is the core that you want the software to design with. Then click on the optimize button and allow the software to present solutions with the additional constraints of device and transformer size. Transformer power processing capabilities are derived using the area-product method (Ae x Aw). Power supply efficiency and switching frequency are factored into this calculation. In all cases, Optimization will choose
