FIG 9 shows a graph of load current ILoad relative to the switching frequency fsw under an embodiment where a hysteresis is added to the control of the switching frequency in order to prevent the oscillation of the switching frequency when the peak value of {HEAD ~ the main switch current pulses} changes between {TAIL ~ two consecutive discrete values}
