1. A driver for driving a load, the driver comprising:
a power converter for converting an input to an output for powering the load; and
a controller for controlling the output of the power converter by controlling a control voltage on a communication line provided in between the power converter and the controller, wherein the controller is arranged to control the control voltage to be within a predetermined control voltage range;
wherein the power converter is further arranged for communicating from the power converter to the controller by overriding the control voltage on the communication line to be outside of the predetermined control voltage range;
wherein the driver comprises the communication line, and wherein:
the controller comprises a control impedance connected to the communication line, and is arranged for controlling the control impedance for controlling the control voltage to be within said predetermined control voltage range.
