An audible noise reduction circuit adjusts either one of the reference voltage, the current sense voltage or the current sense resistor based on a detected switching frequency such that the controller maintains {HEAD ~ the switching frequency} above the audible frequency range in response to {TAIL ~ an adjustment}
