Reference Design for a 7 W, 90-135 Vac, 500 mA LED Driver
Driver efficiency is a function of the LED string forward voltage and input voltage. One of the concerns for long life LED lighting applications is that the LED driver circuitry have a reliability in line with the LED and application use profile. The circuit can be tailored for specific LED ratings to create a reliable long-life lighting solution with lower recovery current to reduce losses and consequently increase efficiency.
