    摘要: A driver circuit, and light emitting system and method are provided. The driver circuit includes possibly a controller and a phase detector coupled to produce an intermittent output proportional to a value of an input relative to upper and lower threshold values, and a difference between the input signal, which is the intermittent output signal, and a reference value. The light emitting system can include a switch and at least one light emitting device coupled to the switch. The driver circuit can be coupled to forward the intermittent output signal to the switch that is active in proportion to current level through the light emitting device, rising and falling between the modifiable upper and lower threshold values.

    摘要: A light emitting driver circuit, system, and method are provided. The driver circuit system and method can be implemented in various ways. An embodiment includes a bypass circuit which diverts current from the LEDs whenever a switch coupled to the LEDs incurs residual current when turned off. In an additional or alternative embodiment, the residual current can be sensed and the amount of residual current used to trigger fetching of a compensation value. That compensation value can change a dimming function forwarded to the switch in order to compensate for, offset, or substantially eliminate the residual current through that switch.
