Dear TI Expert,
I used LM5023 IC for my SMPS of 15Volt,2.5A Output From 3phase 4 wire input AC Supply . I got the required LM5023 IC based schematic design from webench TI Tool.
We did the complete PCB board And under testing condution, we are getting the required output voltage of 15 volt at no load conditon. But under loaded SMPS condition, Output current of SMPS Greater than 0.8A, the output of SMPS voltage is reducing to Zero volage. In our application We need to operate the SMPS up to 2.35A.
How to eliminate this issue of SMPS as mentioned above As voltage reduction of SMPS to Zero at more than 0.8A Load output. I Hereby Attaching schematic and PCB board file of our SMPS and Webench File. Please kindly give a solution as soon as possible.
Thank you
Best Regards,
