Vin=3.5V,Vout=3.3V,load(max)=0.15A, Duty=0.94
when Iload=0.15A,H/S MOS always turn on, Is it correct?

Hi Andy,
The converter will be operating in this condition, so both the HIGH and LOW MOSFETS will be switching.
I am not sure which measurements you have sent, but to verify this you have to measure the SW node voltage. I am attaching a picture of the SW node voltage for your application specs. As you can see, the converter is switching. For more info on how to measure the SW node voltage see this app-note: Understanding the Absolute Maximum Ratings of the SW Node
Kind regards,
Davor
Hi Andy,
Do you have any updates?
If not I would like to close this thread.
