There is provided a process for operating a switch mode power supply circuit (Switcher) connectable to a load, the circuit having a first buck switch, a second boost switch and an inductor in a buck boost circuit, the process including applying input voltage to the circuit, selectively activating each of the buck switch and boost switch, and selectively limiting the ON-time of the buck switch, for accelerating discharge of the inductor.
