This application note describes the characteristics and features of a 130W demonstration board (EVL130W-STRLIG), tailored to 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 strengths of this design are very high efficiency, wide input mains range (85-305 VAC) operation and long-term reliability.
The document details a 130 W demonstration board tailored for LED street lighting applications, featuring a two-stage design: a front-end PFC stage using the L6562AT controller and an LLC resonant converter based on the L6599AT. The design emphasizes high efficiency with a wide input mains range of 85-305 Vac.
| Input mains range | 85 + 305 Vac - frequency 45 + 55 Hz |
|---|---|
| Output voltage | 48 V at2.7A |
| Efficiency at full load | better than 90% at 115 Vac |
| Mains harmonics compliance | EN61000-3-2 Class-C |
| EMI compliance | EN55022-Class-B, EN55015 |
The output voltage is 48 V at 2.7A.
The design uses the L6562AT for the PFC stage and the L6599AT for the LLC resonant converter.
