LED 驱动器，串行升压，带单线数字接口

FAN5345 是驱动串联 LED 的异步恒定电流 LED 驱动器，可确保所有 LED 具有相同的亮度。 FAN5345S20X具有20V的输出电压，最多可驱动5个串联LED。 FAN5345S30X具有30V的输出电压，最多可驱动8个串联LED。 为小外形应用而优化的1.2MHz固定开关频率允许使用小电感和小电容。 FAN5345通过简易单线数字控制接口在32个线性步骤内采用数字脉冲对LED亮度进行编程。为了安全起见，该器件集成了过压、过流、短路检测以及热关断保护。 此外，如果电池电压过低，则会触发输入欠压闭锁保护。 6引脚SSOT23封装中有FAN5345。 • ￭ 异步升压转换器 ￭ 驱动串联 LED： \n• FAN5345S20X： 20 V 输出\n• FAN5345S30X： 30 V 输出￭ 2.5 V 到 5.5 V 的输入电压范围￭ 采用单线式数字控制接口设置 LED 亮度\n• 32 个线性步骤￭ 1.2 MHz 的固定开关频率￭ 软启动功能￭ 输入欠压闭锁 (UVLO)￭ 输出过压保护 (OVP)￭ 短路检测￭ 热关断 (TSD) 保护￭ 6 引脚 SSOT23 小外形封装;
