Light emitting driver circuit with bypass and method
Abstract:
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.
