if the input is less than 42V, we have LM25180 for this application. The 1K price is less than LM5180.

Thanks

In this design transformer limiting the current up to 60mA. Can we connect directly the voltage output from the transformer to TPS26 Vin rather than using Jumper J1?

Kindly explain the purpose of Jumper J1 and J2

Hi Dheeraj,

Apologies for the delay. These jumpers are placed to facilitate individual block testing.

Yes, you can directly connect the voltage output from the transformer to TPS26625.

Best Regards, Rakesh
