TLV62568: OCP/OTP waveform on Vout

Hi Team,

Below is the TLV62569 Vout waveform. (3.3Vin 0.9Vout)

My question here is that do you have comment for the waveform? From my point of view, the voltage drop has regular frequency which means that the load sink the ultra high current frequently to cause IC entering into OCP(H/S SW current limit) How do you think? 

For OTP, I don't think the drop has regular frequency.

In addition, when current reach out to current limit, will SW still do the operation or stop? May I use SW mode to identify the drop is from OCP or OTP?

Regards,

Roy
