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

The STEVAL-ILL053V1 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.

The strengths of this design are its very high efficiency; wide input mains range (85-305 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-ILL053V1 demonstration board offers an innovative design approach using film capacitors from EPCOS in place of electrolytic capacitors.

Thanks to the high efficiency achieved, just a small heatsink for the PFC stage is needed, while the other power components employ SMT (surface mount technology), like most of the passive components, thereby decreasing production labor cost.

The STEVAL-ILL053V1 demonstration board also provides protection against overload or short-circuit, open-loop by each stage, or input overvoltage, with auto-restart.
