TPS54335A: pulse-skip eco mode threshold

Part Number: TPS54335A

Hello

I wonder it may be similar post, but please let me know about threshold of pulse-skip eco-mode(TM).

I had tested skip mode using TPS54335A EVM and electric load.

( I had changed R18 only to adjust Vo=3.3V)

I saw Skip bgean to start below Io= 90mA at Vin=24V.

( alsoI saw skip had began below inductor current  < 360mA approximately .)


Atteched is the  wave form.


Question


Q1  Skip mode begins  depend on inductor current regardless

    of Vin ( if inductoer was same) ? and indctor current threshold for skip mode should be smaller than 500mA?
 
    I saw skip began  if inductor current  was smaller than  360mA  approximately

    and CCM began if Iinductor was greater than 500mA  approximately.

   Is this understanding  correct?
 
    My inductor is 15uH. ( EVM default)


Q2  I think the larger inductor value  ( ex 15uH=>47uH) has lower thershold to enter/exit skip mode if Vin was same,

   but is my understanding  correct? ( I am sorry, I had not tested it yet)

Best Regards
