Dear Sir,
We are working of bring up and testing of DC-DC (Flyback) Converter (VIN: 32 to 75V DC and output 24V and 15W) based on UC3843, We are getting multiple pulses on Gate (Magenta Line in the waveform) and MOSFET Drain to Source (Cyan Line in the waveform), What is the reason for getting these extra pulses, Due to this Line and Load regulation is very poor around 10% and Transformer is giving noise.
What is the possible reason for these extra pulses?
Looking forward to supporting on the same, Thanks in advance.
