A fixed phase power controller that converts a line voltage to an RMS load voltage includes an analog control block with a capacitor that receives an input that is independent of a change in magnitude of the line voltage and that charges and discharges to provide a trigger signal at a first frequency, a reset circuit that periodically resets an initial condition of the analog control block, a synchronization connection that provides a sync signal that synchronizes the trigger signal with a waveform of the line voltage, and a control circuit that clips a load voltage based on the synchronized trigger signal to define the RMS load voltage. The controller finds application in a lamp where it reduces the line voltage to an RMS load voltage suitable for a light emitting element.
