Hi Tao,
I could obtain the additional waveform.
Although it is not below UVLO, there seems to be some places where switching has stopped.
Could you please see attached file and advise?

Part Number: TPS63021 Hi Team,
We are using TPS63021 buck boost regulator in our new design to generate 3.3V.
There are two optional inputs battery and 5V supply,
We require 3.3V/3.5A when input is 5v supply(need buck), also 3.3V/2A when input is con…
Part Number: TPS63021 Hi,
We have followed a recommended design from webench for a 3-4.2V to 3.3V @ 2.5A dc dc converter.
The implemented design however will shut off the output whenever the current goes above 2A.
We exchanged the recommended inductor…
Part Number: TPS63021 Other Parts Discussed in Thread: TPS7H4010-SEP Hi,
I have an application where we are thinking of using the TPS63021 and there will be times when VIN = 0V while VOUT = 3.3V because it is being provided by a second power source.
