【应用】效率高达90%的白光LED驱动芯片SGM3749用于LCD显示屏,集成38V LED开路保护功能,保证高可靠性
某用户的电机控制器,采用了LCD显示屏显示系统相关参数,需要一个高效率的白光LED驱动芯片,来驱动LED灯组做LCD显示屏的背光源。
这里为其推荐国产圣邦微的白光LED驱动芯片SGM3749,主要基于如下考虑:
1、SGM3749是一款效率高达90%的白光LED驱动器,带1.25MHz升压转换器。输入电压范围比较宽,从3V到20V。具有固定的开关频率和内部40V/1.5A开关FET,能够驱动多达10个串联的白光LED。
2、FB反馈电压通常调节为200mV。默认LED电流由外部R设置电阻器编程。在使用过程中,可以通过向CTRL引脚施加PWM信号(其调光频率范围比较宽,从5kHz至100kHz。调光稳定,脉宽调制范围大于1:500)来控制LED电流,可均匀细腻的调节LED亮度,改变LCD显示屏的明亮程度。或者输入高低电平信号,点亮和熄灭LED。
3、SGM3749集成了38V LED开路保护,可防止在LED开启时由于过电压而损坏。自动软启动功能,可减少浪涌电流的冲击。工作温度范围比较宽,从-40℃至+85℃,可以保证可靠稳定工作。SGM3749有TDFN-2×2-6L和TSOT-23-6两种封装,所占用的PCB板空间也比较小。下图是SGM3749应用参考电路图:

【选型】国产LED驱动芯片SGM3752可P2P替换SY7200A应用于温控器,最大输出电压达35V
温控器目前非常广泛的用在办公室,商场以及小家庭里面,可以很方便的控制中央空调。温控器是通过LCD面板来显示温度等相关信息的,LCD本身不会发光,要想让其显示所要的数据,需要使用白光背光源,白色背光源一般由数个发光白色LED灯组成,LED灯的个数由屏的尺寸大小决定,要使LED灯亮,还要使用LED驱动芯片。

【选型】国产可控精密稳压源SGM431XK3G/TR可pin-pin替代TI TL431AIPK,具有更低温漂
工程师在LED驱动电源设计中,通常会用TI的TL431来设计恒流电路,不过受中美贸易战影响,不少厂家需要一款国产高性能芯片替代TI TL431AIPK,本文推荐圣邦微的可控精密稳压源SGM431XK3G/TR,能够Pin-pin替代Ti的TL431AIPK,两者电性能参数基本一致,但SGM431XK3G/TR有着更低的典型温度漂移、动态输出电阻和更高的工作温度,有利于提高系统稳定。
