LM5181: LM5181

Part Number: LM5181

Hi team.

Could you kindly give the reference design for LM5181 for the below specifications:

Input: 18-40V (typ=24V)

Output:

1) 32V, 0.05A;

2) 24V, 0.05A;

3) 5V, 0.05A.

Most interested in turns ratio.

According to table 3 of the LM5181 Datasheet for 16-32V the turns ratio should be 1:2.

However, the "LM5181 PSR flyback converter design tool" (https://www.ti.com/tool/LM5181DESIGN-CALC) does not allow you to set this turns ratio 1:2 (or 1:1.5; 1:3; 1:4). The program crashes.

Can you provide a "LM5181 PSR flyback converter design tool" for calculating the turns ratio 1:2?

Thank you and best regards,

Vyacheslav
