On Semi公司的NCL31000系列产品是高效率LED驱动器,支持高带宽模拟调光和PWM调光,低至零电流.NCL3100包括集成3.3V降压固定DC/DC转换器和可调2.5V-24V 降压DC/DC转换器.诊断区块集成了一个ADC,用来测量输入和LED输出电流,电压,LED温度,DC/DC电压和电流.快速安全机制保护芯片的主要区块,诊断测量和灵活的状态报告以及中断机制一起提供.NCL31001除了不包括两个DC/DC转换器外和NCL3000一样.宽输入电压范围21.5V到57V,专有的100W+应用.器件集成了高效率降压LED驱动器,可调开关频率为44.4kHz到1MHz.器件采用48引脚7x7mm QFN封装,是无铅和RoHS兼容的.主要用在可见光通信的LED灯具以及超市,仓库,医院和机场在内众多空间的照明.本文介绍了NCL31000主要特性,框图和应用电路,以及评估板NCL31000ASGEVB主要特性,电路图,材料清单.

 

The NCL31000 is a new member of the ON Semiconductor LED driver family specifically targeting luminaire applications. NCL31000 incorporates a high efficient buck LED driver. The LED driver supports both high−bandwidth analog dimming and PWM dimming down to zero current. NCL31000 includes an integrated fixed 3V3 DC−DC and one adjustable DC−DC. A diagnostics block incorporates an ADC, which measures input and LED output currents, voltages, LED temperature, DC/DC voltages and currents. Fast safety mechanisms protect the critical blocks of the chip. The diagnostic measurements are available together with a flexible status reporting and interrupt mechanism. NCL31001 is the same as NCL31000 except that it does not include both DC&..
