A method includes receiving a control signal associated with a load, where the control signal is to cause a load change from a perspective of a switching-mode power supply. The method also includes causing the power supply to adjust a current through an inductor of the power supply in response to the control signal. The method further includes delaying delivery of the control signal in order to delay a time of the load change, where the current through the inductor increases during the delay. The control signal could include a request to turn on one or more LEDs. The load could include a current regulator. The method could further include providing the request to the current regulator after the delay, such as after the current through the inductor reaches a specified level. Voltage spikes and audible noise in a capacitor coupled to an output of the power supply can be minimized.
