A DC-DC regulator system includes a power circuit which has a first input coupled to receive an input voltage, a second input coupled to receive a control signal and an output to provide a regulated output voltage. The system includes a control circuit which has a first input coupled to receive the regulated output voltage, a second input coupled to receive a reference voltage, a first output to provide the control signal, and a second output to provide a converter clock signal. The system includes an out-of-audio circuit which has a first input coupled to receive a minimum threshold frequency signal, a second input coupled to receive the converter clock signal, a third input coupled to the power circuit output, and a fourth input coupled to receive a bandwidth control clock signal.
