HI ALL,

I want to check whether my design Vin=16 V,vout =1V is right(UCD9222+UCD7242)? 

But I can't  find the Minimum on-time tON(MIN) parameter  used to calculate the step down ratio.

Best regards,

Die.Rousseau.

    The DRIVER_MIN_PULSE  for the UCD7242 is 20ns and can be found on the Advanced_Config tab on the Configure page of the Fusion Digital Power Designer.

    It is populated automativally by the GUI when the driver selection is made and written on the Design page of the GUI.

    If the Advanced_Config tab isn't visible then go to the File dropdown and click Preferences, then select the Show advanced editors and features which are normally hidden checkbox and click OK.
