Abstract:
1. A buck regulator circuit for providing buck regulation to supply a regulated load current to a load, the buck regulator circuit operable with a buck inductor coupled to the buck regulator at a switch node and to the load at an output node, and with an output capacitor coupled to the output node in parallel with the load, the buck regulator circuit comprising: a switcher circuit operable to provide buck regulation and supply an inductor current through the buck inductor to the load, including charging and discharging the output capacitor; and an analog bypass (ACB) circuit including: wherein the ACB control circuit is configured to receive inductor current information from the switcher circuit, and to provide an inductor current signal representative of the inductor current relative to a predetermined inductor current value and whether the inductor current is positive or negative; and
