Innoswitch3-CE Startup Problem
Posted by: agrawalcomputers

Hi,
I have designed a 14V SMPS using PI Expert.
Please refer to the attached design.
Now if I supply DC input voltage of 300V Using Bench Power Supply, The SMPS does not start.
If I supply DC input voltage between 100-230V it turns on and works.
300V translated roughly to 210V RMS AC Supply.
What could be the problem?
Thanks...

Hi,
Can you provide other details regarding the issue such as loading condition (full load, no load,etc)? It will also be good if you could probe the output and the Drain-Source nodes and show us the waveforms.
Thanks and Regards,
