Zusammenfassung:Methods, devices, techniques, and circuits are disclosed for fast current control of a buck converter. In one example, a device includes a pulse density modulator, an analog comparator, and an interconnect circuit. The analog comparator has a first input connected to a peak current reference. The interconnect circuit has a first input connected to an output of the pulse density modulator and a second input connected to an output of the analog comparator. The device has an output terminal of the interconnect circuit.
