Part Number: LM5180

hi Sir

I want to design a dual output which spec is

Vin=18～36V

Vout=±15V/±0.3A

I follow the design tool for transformer design, but the output is abnormal

Could you help it? I need the transfomer schmatic, thanks

You have designed this already? What is your schematic and what does the output look like?

Hi Alex,

Try using a 1 : 1 : 1 transformer and adjust the feedback resistor to the recommended value.
