STEVAL-ILL053V2 Data brief 48 V - 130 W high efficiency converter with PFC for LED street lighting applications based on L6562 and L6599 Features Extended input mains range: 85 to 305 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 91% at 115 V AC EMI in accordance with EN55022 Class B EN55015 Safety: double insulation, in accordance with EN60950, SELV Dimensions: 75 x 135 mm, 30 mm maximum component height PCB: single side, 35 m, FR-4, mixed PTH/SMT RoHS compliant WEEE compliant Description The STEVAL-ILL053V2 evaluation 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. The strengths of this design are its very high efficiency wide input mains range (85-305 V ) operation and long-term reliability. AC Summary table Because mean time between failures (MTBF) in power supplies is typically affected 48 V - 130 W high by the high failure rate of common electrolytic capacitors, the STEVAL-ILL053V2 efficiency converter evaluation board offers an innovative design approach using film capacitors from with PFC for LED street STEVAL- lighting applications ILL053V2 EPCOS in place of electrolytic capacitors. based on L6562 and Thanks to the high efficiency achieved, only a small heatsink for the PFC stage is L6599 needed, while the other power components implement surface mount technology N-channel 600 V, 0.550 (SMT), which significantly lowers costs. typ., 7.5 A MDmesh STD11N60M2- The STEVAL-ILL053V2 evaluation board also provides protection against overload, M2 EP Power EP MOSFET in a DPAK short-circuit and open-loop in each stage, and overvoltage protection on the input, package with auto-restart.
