I have designed a smps with TNY268 device. The "PI Expert 8" software have chosen EE19 core. But i have an EI25 core at hand and when i wanted to change the core there is no entry for using EI25 and there is other core sizes options. How can i force it to use EI25 core? I have attached the design file. You should change its name to “5v_2.5A.uds”
Thanks in advance.
