LM5045: Seeking Recommendation for PWM Controller for 300W Isolated Full-Bridge DC-DC Converter for EV Application

LM5045: Follow-up for PA3542NL transformer for LM5045 reference design

Tool/software:

Hello,

This is a follow-up to the closed thread regarding the transformer PA3542NL used in the LM5045 reference design.

As advised, I tried contacting Pulse Electronics/Yageo via their contact form and email, but I have not received any response. I also cannot find the datasheet for PA3542NL on their website or distributor portals.

Could TI please help with one of the following:

  1. Provide the datasheet for PA3542NL (turns ratio, pin-out, inductance, isolation, etc.), or

  2. Confirm whether PA3542NL is obsolete, and

  3. Suggest a recommended alternate transformer for the 240W LM5045 reference design.

This information is critical for me to proceed with my design.

Thank you for your support.

Best regards,
Yashaswini M N
