Abstract
A lighting device (e.g. LED driver) includes digital dimming, configuration and firmware updating via wireless communication circuitry and associated volatile memory (e.g., SRAM). A power stage converts AC mains input into a DC bus voltage, and further converts the DC bus voltage into output current for driving a load. A power distribution circuit generates a regulated DC voltage based on the DC bus voltage. A wireless interface circuit is linked to a wireless communications network (e.g., NFC), and configured to receive device configuration data during at least first operating conditions when the regulated DC voltage is unavailable, and further to receive dimming control data during second operating conditions when the regulated DC voltage is available. A controller generates gate driving signals for regulating the output current from the power stage, said gate driving signals generated based at least in part on the device configuration data and the dimming control data.
