Abstract
Pseudo-digital light-emitting diode (LED) with secondary-side flyback control is described. In one embodiment, a Digital Addressable Lighting Interface (DALI) compatible driver includes a secondary-side controller coupled to a secondary winding of a transformer and coupled to a light-emitting element. The secondary-side controller includes a DALI-compatible interface to receive information. The secondary-side controller communicates a control signal with a primary-side controller via a galvanically-isolated link. The primary-side controller is coupled to a primary winding of the transformer. The DALI-compatible driver modifies a light output of the light-emitting element in response to the information.
