The multi-stage off line LED driver

Although it is relatively straightforward to design a basic LED driver for a general lighting application, it becomes far more complex when additional functionality such as phase cut dimming and power factor correction are also required. A non-dimming LED driver with no power factor correction generally consists of an off line switching power supply configured to regulate the output at a constant current. This is not much different from a standard off line switching power supply such as the types commonly used in AC-DC adaptors. Such designs can be based on standard SMPS circuit topologies like the Buck, Boost or Flyback converter.
