Hi,

For the gate drive cards it is SN6501 + 750343725 push pull transformer

For other bias supplies on board it is SN6505B + 750313638 push pull transformer

Thank you

Thank you for your response.

I could see that the turn ratio is 1.3:1 for all the 750313638 family. In the "Design Guide: TIDA-010054" under the voltage sensing (Fig.30), primary voltage is 5V and the secondary voltage is 6V. This means a turn ratio of about 0.83. This contradicts the quoted turn ratio of 1.3:1 in the 750313638 datasheet. I am sure I am not getting something right. Please advise.

Regards,

Olutayo
