NXP SSL5301T 12W调光LED电源解决方案

NXP公司的SSL5301T是可调光控制器,具有高可调光兼容性,调光范围大,单级拓扑PCB占位面积小,集成了起动JFET,可选择模式以得到高功率系数或低波纹,使得LED电源较宽,主要用在通用LED照明.本文介绍了SSL5301T主要优势和特性,框图,几种典型应用电路以及12W评估板SSL5301DB1213主要指标,电路图,材料清单,PCB元件布局图和变压器T1电路与主要指标..

The SSL5301T is a mains dimmable controller IC, intended to drive dimmable LEDs in general lighting applications.

SSL5301T主要优势:

• High dimmer compatibility
• Selectable modes for high power factor or low ripple, allowing a wide LED power range
• Large dimming range
• Single stage topology for small PCB footprint
• Ease of design-in
• Integrated start-up JFET
• Low electronic Bill Of Material (BOM)
• Supports multi-lamp applications
• Various converter topologies supported

The IC drives an external switch for easy power scaling. It has been designed to start up directly from the High-Voltage (HV) supply by an internal high-voltage current source. Flyback, buck and buck-boost circuit topologies are supported. Primary side sensing provides accurate output current control.
