Abstract
A power supply includes power circuitry configured to provide DC power to a separate load, and wireless communication circuitry for wirelessly communicating with an external control device such as a smart phone. A controller is configured to (1) conduct communications with the external control device via the wireless communication circuitry to receive configuration parameters, and (2) incorporate the configuration parameters into a control scheme for operation of the power supply. The power supply may be used with an LED lamp including a series of LEDs, and the configuration parameters establish desired operating characteristics including selection of constant-current or constant-voltage operation, and/or parameters for a dimming curve applied in dimming operation of the LED lamp. The power supply may be used in other applications including battery charging applications.
