My SMPS is designed with the help of PIExpert & Its rated for +5V/1A, +24V/500mA. The design is tested with 1st version of PCB design (Bigger one) & its working fine. The same PCB is redesigned for size optimization. Now the PCB is not working. I have assembled 2 PCB of new design & both not working. While testing the output with DSO, the controller trying to oscillate & immediately turned off. So some frequent spikes of voltages are appear at the DC output terminals. Unfortunately I can't use the working PCB due to the size consideration.
Please advise me to solve the problem. I can redesign the circuit with 2 layer PCB also but I want to know which side (Primary of secondary) & what correction I should be do for my next design. Any commands will be helpful to me...
Thanks & Regards
