Hi,
Customer is troubled because TPS543B20 output voltage is not stabilized.
Could you check the attached waveform?
TPS543B20 wave form .pdf
I got the following question from a customer.
■Is pattern2 out put oscillating? And Is output stopped correctly with understanding OVP?
■When changing from pattern 1 to pattern 2, please tell me the reason for oscillation
■Duty is sparse in pattern 2. Please tell me the reason.
■Is the pulse skipping operation of pattern 3 normal operation?
Please tell me the reason for pulse skipping.
Best Regards,
