STEVAL-ILL052V1 48 V - 130 W high efficiency converter with PFC for LED street lighting applications based on L6562 and L6599 - European version Data brief Features Extended European input mains range: 177 to 277 V - frequency 45 to 55 Hz AC Output voltage: 48 V at 2.7 A Long-life electrolytic capacitors not used Mains harmonics: in accordance with EN61000-3-2 Class C Efficiency at full load: greater than 90% EMI: in accordance with EN55022 Class B Safety: double insulation, in accordance with EN60950, SELV Dimensions: 75 x 135 mm, 30 mm maximum The STEVAL-ILL052V1 demonstration board also component height provides protection against overload or short- circuit, open-loop by each stage, or input No heatsinks needed overvoltage, with auto-restart. PCB: single side, 35 m, FR-4, mixed PTH/SMT RoHS compliant Description 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 V ) operation, and long-term reliability. AC 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.
