Infineon XDPL8220 100W无闪烁LED驱动参考设计
Infineon公司的XDPL8220是高度集成新一代器件,组合了边界模式PFC和准谐振FB控制器以及初级边调整,从而节省了外接元件和优化了性能,通用AC输入(90-305VAC)或DC输出(90-305VDC),可用功率范围20W到150W,多控制模式(恒流(CC)/恒压(CV)/有限功率(LP),效率大于90%,主要用在LED照明的电子控制(ECG).本文介绍了XDPL8220主要特性,框图,型应用电路图以及参考设计REF-XDPL8220-U100W主要特性与优势,电路图和PCB设计图.
XDPL8220 is a highly integrated next-generation device combining a boundary mode PFC plus a quasi-resonantFB controller with primary-side regulation. The integration of these functions enables saving of external partsand optimizes performance by harmonized operation of the two stages.
XDPL8220 uses a constant on-time scheme with a THD improvement algorithm to provide a high power factorand excellent THD performance.
With its unique control scheme of CV, CC and LP, the LED driver designer is provided with a large degree offlexibility and can utilize the system hardware to its limits.
