NXP SSL2109T GreenChip 23W LED照明控制方案
NXP 公司的SSL2109T是高压集成电路,是GreenChip LED照明控制器,具有小PCB面积,效率高达95%.参考设计能工作在230V(50 Hz)或120VAC(50 Hz 或60 Hz),输出电压30V或更高,最大输出功率23W.本文介绍了SSL2109T主要特性,方框图,典型应用电路以及参考设计板主要特性和指标,电路图,材料清单和PCB布局图.
The SSL2109T is a high-voltage Integrated Circuit (IC), intended to drive LED lamps in general lighting applications.
SSL2109T主要特性:
•Small Printed-Circuit Board (PCB) footprint, and compact solution
•High efficiency (up to 95 %)
•Ease of integration and many protection features
•Low electronic Bill Of Material (BOM)
The IC is supplementary to the SSL2108X series, but without internal switch. The IC range has been designed to start up directly from the HV supply by an internal high-voltage current source. Thereafter, the dV/dt supply is used with capacitive coupling from the drain, or any other auxiliary supply. This functionality provides full flexibility in the application design. An internal clamp limits the supply voltage.
