LM5088: Operation method for emulated current mode control on DCM condition

Satoshi

Part Number: LM5088

Please let me confirm about emulated current mode control on light load or no load condition.

When inductor current become less than 0A (equal to DCM), I think that LM5088 and negative valley current can not keep DC level, is it correct? 

If correct, how is the change for DC level on DCM?

Best regards,

Satoshi
