    Abstract: Employed within an LED driver (600) operating from the AC power line (120), the invention controls both input current and output power. With the regulation circuit (610, 620) desribed, input current appears purely resistive, precisely tracking the input voltage waveshape. At the same time, it provides good line regulation and inherent phase dimmer compatibility, requiring no special circuitry to detect and handle a dimmer.
