Hi James,

Sorry there is no design calculator on the website, I will ask our applications team if there is one we can send to you.

Hi James,

Unfortunately, we currently do not have a calculator tool available for the LM5025A. If you could send me your design requirements, I would be happy to assist with the transformer calculation.

Best Regards,

Hi James,

I would like to offer some resources that could help you with your active clamp forward application

You can find equations for active clamp forward primary/secondary currents starting on page 91 of this guide:www.ti.com/.../slyu036.pdf.
You can also use power stage designer which will help calculate turns ratio, magnetizing inductance, etc:www.ti.com/.../powerstage-designer.
Make sure to set the maximum duty cycle appropriately in the tool. For LM5025A, the max duty cycle is 80%.

Best Regards,
Ben Lough
