[原创] Infineon ICL5101130W LED电源解决方案

Infineon公司的ICL5101集成了PFC的谐振准控制器,支持通用的输入电压和宽输出电压范围,功率因素修正大于99%,THD小于5%,效率高达94%,超快点亮时间小于200ms,主要用在LED驱动器如大于50W的商业或住宅区照明系统,LED照明的电子控制装置.本文介绍了ICL5101产品亮点,主要特性和典型应用电路,以及130W CC LED电源演示板主要特性,电路图,材料清单和PCB设计图.

The LED Resonant controller ICL5101is designed to control resonant convertertopologies. The PFC stage operates in CrCM andDCM mode, supporting low load conditions. Integrated high and low side drivers assure a lowcount of external components, enabling small formfactor designs.

ICL5101 parameters are adjusted by simpleresistors only, this being the ideal choice to easethe design-in process. A comprehensive set ofprotection features ensures that the LED driverdetects fault conditions, protecting both the LEDdriver and the LED load. Figure 1shows a typicalapplication circuit of a 110 W constant voltage LEDdriver.

ICL5101产品亮点:

Resonant Controller and PFC within one IC
Supports universal input and wide output range
Low count of external components supportingsmall form factors and improved reliability
All parameters set by simple resistors only
Supports outdoor use by extended junctiontemperature range from -40℃ to +125 ℃..
