What could be the probable reasons for this sort of waveform, in other words what what does this waveform indicatewaveform.docx

Can you provide a schematic and operating parameters of your design? Is the output voltage regulating correctly for what you designed for or not? Does this occur over all power levels and input voltages, or just certain conditions? Also can you capture waveforms of the output voltage(s) and voltage at the CS pin? It's hard to say what's going on without more information since several things could be happening.
