Post LPD6803
我司自主研发的LPD6803驱动IC芯片,广泛运用于LED灯市场,如:护栏管、点光源、灯条、灯带、穿孔灯、LED显示屏等。
LPD6803是专为LED灯光系统设计的驱动芯片,它采用先进的高压CMOS工艺,提供三路恒流驱动和灰度调制输出,特别适合离散的多灰度全彩色灯光系统。
LPD6803芯片包括串行移位寄存器和级联驱动电路,灰度数据再适中上沿移入串行移位寄存器,转储后经脉宽调制转为3端口并行输出,串行移位寄存器和灰度计数器可以由不同的时钟信号控制。同事,LPD6803将数据和控制信号经内部驱动后输出给下一级电路。
特性:
三路驱动输出,每路最大电流达45MA,LED灯电压可达12V
输出级采用IN-RUSH在线反馈模式的恒流驱动结构,兼容恒压驱动模式,也可以外接器件转换成更高电压或电流的输出驱动
内置LDO稳压电路,供电范围可达3-8V,并有5V稳压输出
采用自增码令牌技术的双线移位总线,移位时钟可达25MHZ
直接输入灰度数据,经内部SUPER-PWM技术转化为带反伽马校正的256级输出,如采用内置振荡器作为灰度时钟,支持不间断FREE-RUN调制输出,特别适合低成本控制器应用
数据时钟信号经过内置锁相再生电路,强驱动后提供给下级芯片以提高级联级数
高压CMOS工艺,工业级设计,抗抗干扰性能极强
符合ROHS环保要求的SOP16/QFN16无铅封装,也可提供COB封装或DIE裸片
