I was studying about boost converter and i was confused about term 'PFM' and 'DCM'.
If I understood these correctly, PFM is pulse frequency modulation which modulate output voltage by changing the frequency of switch when load out current is low.
DCM is discontinuous current mode which occurs when load out current gets low so inductor current goes to zero.
do they have any relationship?
and also i heard in particular application, people use PFM, DCM in purpose.
What is the advantage of using these modes?
