This reference design is a constant current input boost converter for LEDs which utilizes the LM5020-2 controller. The design features switch current limiting and input under-voltage lockout. Input voltage regulation from a constant current source provides constant output power to the load. For LEDs with relatively constant output voltage, the output current is proportional to the input current.
