EVL130W-SL-EU(1): 48V @ 2.7A, 177 ~ 277 VAC

Summary

* For Constant Current, the board must be modified as described on page 6 of the user guide. *

This application note describes the characteristics and features of a 130 W demonstration board (EVL130W-SL-EU), tailored on an LED power supply specification 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 peculiarities of this design are; very high efficiency, extended European input mains range (177-277 VAC) operation, and long term reliability.

Because reliability (MTBF - “Mean Time Between Failures”) in power supplies is typically affected by electrolytic capacitors and their typical high failure rate, unless using very expensive types, this board offers a very innovative design approach as the board doesn't implement any electrolytic capacitors, which are replaced by film capacitors from EPCOS.
