STEVAL-ILL053V2: 2.7A @ 48V Max, 85 ~ 305 Vin

Summary

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.

Thanks to the high efficiency achieved, only a small heatsink for the PFC stage is needed, while the other power components implement surface mount technology (SMT), which significantly lowers costs. The STEVAL-ILL053V2 evaluation board also provides protection against overload, short-circuit and open-loop in each stage, and overvoltage protection on the input, with auto-restart.
