Driver device (1) and a corresponding driving method for driving a load (100), in particular an LED assembly comprising two or more LEDs. The proposed driver device comprises supply terminals (10) for receiving a supply voltage (Vs), load terminals (20) for coupling a load to said driver device and for providing electrical energy to said load for driving said load, a storage unit (40) for storing electrical energy received at said supply terminals, a coupling unit (50) coupled between said supply terminals and said storage unit for controllably providing electrical energy from said supply terminals to said storage unit, a first switching unit (60) coupled between said supply terminals and said load for switchably providing electrical energy from said supply terminals to one or more of said load terminals, a second switching unit (70) coupled between said storage unit and said load for switchably providing electrical energy stored in said storage unit to one or more of said load terminals, and a control unit (80) for controlling said coupling unit and said first and second switching units.
