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