STMicroelectronics STEVAL-ILL053V2, STEVAL LED Evaluation Board for L6562, L6599 for LED Street Lighting

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 VAC) operation and long-term reliability.
Because mean time between failures (MTBF) in power supplies is typically affected by the high failure rate of common electrolytic capacitors, the STEVAL-ILL053V2 evaluation board offers an innovative design approach using film capacitors from EPCOS in place of electrolytic capacitors.
