Abstract:
At least one exemplary embodiment is directed to a method of switching between synchronous and nonsynchronous ramp control. An embodiment may include a power supply controller that has a trigger circuit configured to generate an RPM trigger, a timer circuit configured to generate a clock signal, and a switching circuit configured to switch a modulation mode responsively to the clock signal and the RPM signal.
