I read this previous question:

https://electronics.stackexchange.com/questions/285029/the-meaning-of-burst-mode

It says burst mode happens when the resistance of the load is light and the system stops switching the MOSFETs. However I just cannot understand how the light load decreases the load current and therefore the inductor current, as mentioned in the link.

As I know \$Vload=Rload*Iload\$ and \$Vload=D*Vin\$. So if we have low load and highest input voltage, this implies that duty cycle is small and the current is going high - which means the inductor current must be high as well and never goes to DCM! What I am missing?
