In one embodiment, a driver circuit for light-emitting diodes has a first DC/DC converter (DCDC1) with an input (IN) for feeding a supply voltage (VBAT) and with a first output (OUT), a second DC/DC converter (DCDC2), which is coupled on the output side to the first output (OUT) and is designed for operation with energy supplied in advance, a current source (IFlash) that is connected to the first output (OUT), and a main output (LED_OUT), which is coupled to the current source (IFlash) and is designed to be connected to the light-emitting diodes. The first DC/DC converter (DCDC1) is designed for operation in a current-limiting mode. The second DC/DC converter (DCDC2) is designed for regulation to a nominal voltage (Vds) of the current source (IFlash).
