Duty cycle and Mode of operation

Akash S

Part Number: PMP7899

Hi,

What is the operating duty cycle of the current design? Does it operate in CCM or in DCM?

Hello Akash,

The test report shows CCM operation at full load. See the switching waveforms for duty cycle. DCM will occur at lighter load.

You can use Power Stage Designer 4.0 to calculate operating mode and duty cycle at any line and load condition.
