hi all,

Is it possible to design Synchronous buck converter using PWM control for DCM operation?

Thanks
 

Yes, If you disable the low side mosfet at light output currents. This is often called diode emulation. This action also, boosts the effficiency because the converter is not recycling current from the output back to the input.
