Constant current LED drivers
While high power LEDs need complex driver schemes, the vast majority of applications use LEDs with currents below 500 mA and can be driven by linear constant-current LED drivers. These are easy-to-use, reliable, cost efficient, and do not affect EMC. This article gives a short overview on the design and power considerations necessary to use constant-current LED drivers in practical applications.
