A BUCK CONVERTER WITH A CURRENT-MODE REGULATOR
A current-mode regulator relies on indirect current measurement to facilitate slope compensation used to stabilize the operation of a buck converter. The current-mode regulator comprises an inductor, a switching network, and a controller. The inductor delivers an output current to a load. The switch...

| description | A current-mode regulator relies on indirect current measurement to facilitate slope compensation used to stabilize the operation of a buck converter. The current-mode regulator comprises an inductor, a switching network, and a controller. The inductor delivers an output current to a load. The switching network selectively connects the inductor input to an input voltage or a second voltage. The regulator controls the switching network. An inner loop control circuit of the regulator comprises the switching network, a current measuring circuit, a slope circuit, a comparator, and a switching controller. The current measuring circuit comprises a passive network connected to the inductor input and operative to indicate an inductor current as a measurement voltage. The slope circuit applies a time-varying voltage having a positive slope to the measurement voltage. The comparator compares a slope compensated measurement voltage to the control voltage. The switching regulator controls the switching network in response to the output of the comparator. |
