any1 can teach me how to differentiate the discontinous current mode & continuous current mode???

is it based on the delay in btwn 2 gate trigger input?? or based on the output voltage goes to zero or not??


really thx a lotsssss
 

CCM means the inductor current wont be zero ,but DCM means the current will reach zero,it always happen in a low load
 

if let's say i dun have a inductor ,but i have a capacitor, so it's depend on the capicitor current??
