Power Adapter Product: Issue on current rating

Hi TI Engineers,

I have a customer asking for a design support on their product which is Power Adapter 12V 6A (72watt).

Issue: Current rating is not fully delivered and heating issue is present.

The Customer did a great business and sold around 100k units of same module to the company X

The demand is continues but there is some issue in designing or component selection .

  • Customer needs support in designing the circuit and
  • Selection of components from TI like:

             MOSFET

             Controller IC 

             Top switch etc.

The customer provided their schematic diagram and BOM. I could possibly send it however it should be confidentially.

Looking forward to your support.

Thank you.

Best regards,

Julie Ann
