A chipset for powering and controlling a plurality of light emitting diode (LED) strings. The chipset includes a controller having a pulse width modulating (PWM) functionality and a data transfer interface circuitry; and at least one dissipative active element array comprising a plurality of dissipative active elements. The dissipative active element array(s) are packaged to be thermally separate from the controller. The PWM functionality is arranged to individually pulse width modulate a current flow through each of the LED strings. Each of the plurality of dissipative active elements is associated with a particular one of the plurality of LED strings and is arranged to limit the current flow of the pulse width modulated current that flows through the particular LED string to a value, the value being responsive to a value output by the controller via the data transfer interface circuitry.
