To achieve a high efficiency over a wide load range, the converter enters a power saving pulse-frequency modulation (PFM) mode at light load currents. And the proposed buck converter features an automatic mode change between pulse-width modulation (PWM) and PFM depending on the load current ...
network. We’re guessing that the op-amp driver won’t make this the most powerful of switchers, but in this case that’s hardly the point. Build this if you’re interested in taking an op-amp out of its normal sphere, or if you’re interested in the workings of a buck converter....
