A switched mode power supply (SMPS) designed for LED lighting applications is an LED driver that uses a switching regulator to convert the rectified DC power into a predetermined magnitude of DC power. SMPS LED drivers provide the most efficient and technically mature solution to LED current control. Today’s LED lighting products, in particular those designed for high end applications, place high demands on the driver’s ability to efficiently convert electrical power from an AC source to a DC load with outputs matched to the electrical characteristics of the LEDs. Despite the increasing cost and form factor restrictions in LED luminaire design, switched mode power supplies are still the most preferred type of power converters to drive high performance LED luminaires.
