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 {HEAD ~ the controller} maintains the switching frequency above the audible frequency range in {TAIL ~ response} to an adjustment
