InnoSwitch3-MX隔离型开关IC配合使用时,InnoMux控制器IC通过将ACDC和DCDC变换器替换为单级反激拓扑,可大幅简化显示器和电视机的电源设计。这有助于减小PCB占板面积,并极大提高系统效率。

LED背光控制可提供出色的最小阈值调节,以及在模拟和多个PWM调光方式之间进行选择。序列PWM调光选项可进一步改善视觉表现并稳定所需功率。此外,还可提供更全面的保护特性。

产品特色

恒压和4通道LED背光控制器

  • 可省去降压变换器和LED背光升压变换器
  • 一个或两个恒压输出
    - 独立稳压输出,即时快速的动态响应特性可保证以0%-100%-0%负载阶跃提供±5%的恒压控制精度
  • 典型输出电压
    - 一个恒压输出的模式:5 V到22 V
    - 两个恒压输出的模式:5 V和12 V到22 V
  • 1-4串LED背光
    - 提供3%的LED灯串匹配精度
    - 模拟、PWM、序列PWM和滤波PWM工作模式
    - 灯串电压可达100 V/灯串总电流可达960 mA
    - LED灯串电压范围可达2:1

先进的保护/安全特性

  • 所有输出均具备独立的过载保护
  • 灯串不平衡/短路/开路保护
  • 输出过压时进入自动重启动保护

便捷的封装

  • 适合单面波峰焊PCB的28引脚HSOP封装,或者适合紧凑型多层设计的小型28引脚QFN封装(5x5 mm封装体)
