Abstract
A circuit includes a switching power converter and a load current management circuit. The switching power converter provides a first current that varies between a first current value and a second current value in response to a dimming control signal. The load current management circuit provides a second current that varies between the second current value and a third current value in response to the dimming control signal. The second current varies in accordance with the first current. For example, the second current increases as the first current decreases and the second current decreases as the first current increases. In one example, the second current value corresponds to a required minimum load current for the power converter to regulate an output voltage.
