i was simulating a simple dc-dc buck converter with open loop control with switching frequency 25 kHz..The buck converter is meant to operate in discontinuous conduction mode...For a particular resistive load(say 30 ohm) ,it gives a constant output voltage in DCM .But, when i am varying the load (say 60 ohm), there is a change in the output voltage(consider all other parameters remaining constant):thinker::thinker:But the voltage should remain constant in a particular range of the load..

May be varying the load is affecting the OFF time.Hence it is affecting the load voltage.....
