LM5020: 54V to 12V/1A reference design

Hi Nicole,

This is a close reference design: https://www.ti.com/tool/PMP21002

You can use section 3.2.1 and 3.2.2 as a design guidance for the transformer in a flyback topology. 

Please let me know if you have any other questions,

Richard. 

Hi, Richard,

Where is the section 3.2.1 and 3.2.2? I didn't find it from LM5020 datasheet.

Is there LM5020 design calculator for Flyback topology in excel format available

Hi Nicole,

Sorry for the delay in response. I should have linked this to the following application note: https://www.ti.com/lit/an/snva866/snva866.pdf?ts=1627490663596&ref_url=https%253A%252F%252Fwww.google.com%252F

Although it is for LM5155, the inductor design process is the same. 

Thanks,

Richard

HI Nicole,

Unfortunately, there is no flyback design calculator currently available for LM5020. 

Thanks,

Richard
