POWER SUPPLY SYSTEM WITH CURRENT COMPENSATION

A power supply system includes a current driver circuit (2), a sensor circuit (3), a control circuit (4), a voltage generator circuit (5) and a signal generator circuit (6). The current driver circuit (2) generates, based on a pulse signal (GATE), an output current (IL) for driving a load unit (100) that includes series connected loads (1). The sensor circuit (3) senses the output current (IL) to generate a sensed voltage (VSense). For each load (1), the control circuit (4) is operable, based on a control input, to allow or not to allow the output current (IL) to flow through the load (1). The voltage generator circuit (5) generates a reference voltage (VREF_COM) based on the control input. The signal generator circuit (6) generates the pulse signal (GATE) based on the reference voltage (VREF_COM) and the sensed voltage (VSense).
