48 V - 130 W high efficiency converter with PFC for LED street lighting applications based on L6562 and L6599 - European version

The STEVAL-ILL052V1 demonstration board implements a 130 W LED power supply for street lighting.

The circuit is composed of two stages: a front-end PFC using the L6562AT and an LLC resonant converter based on the L6599AT.

What distinguishes this design is its very high efficiency, extended European input mains range (177-277 VAC) operation, and long-term reliability.

Because reliability MTBF (mean time between failures) in power supplies is typically affected by the high failure rate of electrolytic capacitors, unless using very high-end, expensive types, the STEVAL-ILL052V1 demonstration board offers an innovative design approach using film capacitors from EPCOS in place of electrolytic capacitors.

Thanks to the high efficiency achieved, no heatsinks are required.

The STEVAL-ILL052V1 demonstration board also provides protection against overload or short-circuit, open-loop by each stage, or input overvoltage, with auto-restart.
