Product List
Often, audible acoustic noise can be generated when operating at low switching frequencies. Thanks to the R3 modulator, the ISL9237 and ISL9238 deliver the smallest energy transfer per cycle while the switching frequency is reduced or in discontinuous conduction mode, resulting in no audible acoustic noise. Competitor parts use larger bursts to transfer energy, resulting in an audible hum.
