Abstract: An integrated circuit including a buck converter having an integrator and a shunt resistor is described. The buck converter may operate in a continuous conduction mode (CCM) and a discontinuous conduction mode (DCM). The integrator may be coupled to the buck converter to generate an output voltage based on adjustment of a detected voltage across a load of the buck converter within range of a reference voltage. The shunt resistor may be coupled to the integrator configured to maintain the output voltage of the integrator during the DCM.
