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.

Implementing a buck converter supporting automatic continuous conduction mode and discontinuous conduction mode

A power converter includes a plurality of power stages configured to generate an output current that has an output voltage, based on an input current that as an input voltage. The plurality of power stages comprises a first power stage and one or more additional power stages. The power converter also includes a control circuit coupled to the plurality of power stages. The control circuit is configured to periodically turn on each of the plurality of power stages. The control circuit determines a respective time delay between turning on the first power stage and turning on each of the one or more additional power stages based on a switching time-period of the first power stage.

Constant-on-time power converter with adaptive interleaving

A power converter includes a plurality of power stages configured to generate an output current that has an output voltage based on an input current that as an input voltage a control circuit coupled to the plurality of power stages. The control circuit is configured to control operation of the plurality of power stages. The control circuit includes a plurality of constant-on-time loops for the plurality of power stages. The power converter is configured to operate in a single-phase mode or a multiphase mode. A first power stage of the plurality of power stages supports a continuous conduction mode and a discontinuous conduction mode when the power converter operates in the single-phase mode.
