摘要：
The invention relates to a driver device for a load (11), particularly an LED/OLED unit (12; 20, 22), comprising a shunting switch (30) parallel to the load, a control unit (14, 26) for controlling the shunting switch (30), an energy storage element (40) adapted to supply energy to at least the control unit (14, 26), and a recharge control circuitry (46) arranged in series with the energy storage element (40), the series connection of energy storage element (40) and recharge control circuitry (46) being provided parallel to the shunting switch (30), wherein said control unit (14, 26) is adapted to activate said recharge control circuitry (46) and to switch said shunting switch (30) off, when said energy storage element (40) is to be recharged. The invention also relates to a method of driving a load (11).
