NXP SSL4101T 48V 150W LED驱动电源解决方案

NXP公司的SSL4101T是GreenChip III+第三代绿色开关电源控制器,集成了PFC和反激控制器,内置的绿色功能能使在所有的功率等级上具有高效率.SSL4101T是多芯片模块(MCM),包含两个芯片,适用于70 V (AC)到305 V (AC)电压,极少外接元件,并即有多种保护特性,适用于10W-300W间的所有的LED照明应用.本文介绍了SSL4101T主要特性和优势,方框图,典型配置图和应用电路图,48 V/150 W演示板(v.1.1)主要特性和指标,电路图,材料清单和PCB布局图.

The GreenChip III+ is the third generation of green Switched Mode Power Supply (SMPS)controller ICs. The SSL4101T combines a controller for Power Factor Correction (PFC) and a flyback controller. Its high level of integration allows the design of a cost-effective LED lighting application power supply with a very low number of external components.

The special built-in green functions provide high efficiency at all power levels. This applies to quasi-resonant operation at high power levels, quasi-resonant operation with valley skipping, as well as to reduced frequency operation at lower power levels. At low power levels, the PFC switches off to maintain high efficiency.
