About this manual

This document describes the characteristics and features of the EVL130W-SL-EU 130 W demonstration board, designed for LED street lighting. The circuit utilizes a two-stage topology: a front-end Power Factor Correction (PFC) stage using the L6562AT controller and an LLC resonant converter based on the L6599AT. A key design feature is the elimination of electrolytic capacitors in favor of film capacitors to increase Mean Time Between Failures (MTBF) and ensure long-term reliability.
