EVL130W-STRLIG(1): 48V @ 2.7A, 85 ~ 305 VAC

Summary

* For Constant Current, the board must be modified as described on page 8 of the user guide. *

Streetlight applications require that the power supply designed to power an LED lamp must have high efficiency and at least an equivalent lifetime in order to guarantee maintenance-free operation during the life of the LED.

This application note describes the characteristics and features of a 130 W 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.
