摘要： An LED driver drives a plurality of light emitting diodes (LEDs) having first terminals connected to a common output stage and second terminals respectively receiving different, suitably rectified, phases of a sinusoidal signal. An output stage of the LED driver includes a first bipolar transistor coupled between a first supply terminal and the first terminals of the LED's. A first MOS transistor drives the base of the first bipolar transistor. The gate of the first MOS transistor is coupled to a first reference voltage. A second bipolar cascode transistor is connected in series with the first MOS transistor and biased by a second reference voltage such that the voltage across the first MOS transistor does not exceed a limit value.
