    摘要: A switching regulator (2-5) supplies a controllable stable average current to a load (1), such as series-connected light emitting diodes. A regulator controller (2) includes a hysteretic comparator (12, 30) which controls a switch in the form of a transistor (15) for switching current into an inductor (3). The comparator (12) has upper and lower thresholds. A first circuit comprising a fast current monitor (6) supplies a first signal to the comparator representing the instantaneous current in the inductor (3). A second circuit (36, 37, 41, and 42) supplies a second signal to the comparator representing an error between a desired regulator output and an actual regulator output.
