FAN7346 是一款 LED 电流平衡控制器，控制 4-LED 阵列，使其保持相同的 LED 电流。FAN7346 具有较高耐压，因此适用于边缘型 LED BLU 和 LED 照明。为了最大程度减少主节点和辅助接点之间的组件数量，FAN7346 会生成一个新的集成反馈信号。FAN7346 提供了多种保护，如过电压调节、开路 LED 保护、高温保护和调节开关的漏极-源极电压保护（FAN7346 监控所有 LED 镇流的漏极-源极电源以提供保护）。为了提高系统可靠性，FAN7346 采用单个的串保护。因为 FAN7346 集成了这么多功能，所以降低了总体 BOM 成本。通过向 PWM 引脚应用脉宽调制 (PWM) 信号，可以对 LED 亮度进行线性变化以达到 LED 电流。FAN7346 采用 28-SOIC 封装。
