When a diode rectifying DC/DC converter is used in discontinuous operation, could there be an adverse effect on the IC or the peripheral components? What measures could I take if there were such an effect?
In the case of discontinuous operation, when there is a change in the load current such that operation changes from discontinuous to continuous, the transient response is slower, so that the output voltage change is somewhat larger. As measures to address this, there are such methods as increasing the capacitance of the output capacitor or increasing the inductance of the output inductor to set a ripple current that does not result in discontinuous operation.
