EVL130W-STRLIG(2): 48V @ 2.7A, 85 ~ 305 VAC

Summary

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 L6562A 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.
