A single-inductor multi-output DC/DC converter according to a first invention of the present application comprises: a single-output multi-output DC/DC conversion unit; a deviation voltage output unit for outputting a plurality of deviation voltages by comparing each voltage of multi-output of the conversion unit with a predetermined reference voltage; and a switching control unit for summing the deviation voltages to generate a deviation sum voltage, increasing an upper limit reference current when the deviation sum voltage is higher than an upper limit reference voltage, and decreasing a lower limit reference current when the deviation sum voltage is lower than a lower limit reference voltage. Therefore, the single-inductor multi-output DC/DC converter can reduce output ripples by changing upper and lower limits of a current flowing through an inductor at the same time in response to a change in the amplitude of a load current and can adaptively respond to an increase or decrease in the number of output nodes by adjusting the current flowing through the inductor according to an increase or decrease in the deviation sum voltage of a plurality of loads.;COPYRIGHT KIPO 2016
