NXP SSL2101 7.5W反激LED驱动参考设计

采用NXP公司 SSL2101 的7.5W 120V可调光的LED驱动器的参考设计采用反激式转换器,提供隔离的解决方案。参考设计支持5个LED(输出电流470mA)和7个LED(输出电流340mA)负载,输出功率大约为7.5W,效率大约为72%,适合于GU10灯。本文介绍了7.5W反激LED驱动参考设计主要指标,驱动5个和7个LED的演示板电路图以及相应的材料清单和PCB布局图。

SSL2101 120 V 7.5 W GU10 flyback reference board

This document explains the operation and application of a 7.5 W 120 V dimmable LED driver featuring the SSL2101. The demo board has a form factor that is compatible with the base of a GU10 LED lamp. The board employs a flyback converter to provide an isolated solution for mains-dimmable LED recessed-light applications.

The board is available in two different versions, designed to support both a 5-LED and 7-LEDs load with an output power of approximately 7.5 W. The board operates at approximately 45 kHz and produces a regulated output current of 470 mA for the 5-LED load or 340 mA for the 7-LED load, with an efficiency of around 72 %. Both versions are fully compliant with EMC regulations. Key features of the board include:

Deep dimming capability

Wide dimming compatibility

Small form factor tailored to fit a GU10 lamp

Cost effectiveness
