概览

FAN5624 是一款四通道灌电流线性 LED 驱动器，用于为移动电子设备（例如蜂巢手机）中的主 LCD 显示器或键盘提供背光。
50mV的极低压差可在无任何电感或开关电容的情况下驱动LED。 LED输出的亮度通过单线数字控制接口编程。 用户可以编程32个线性调光步骤，通过在该接口上施加数字脉冲来启动或关闭LED。
由于该LED驱动器具有低压差，FAN5626线性LED驱动器能提供较高的效率。 通过完整的32个调光步骤，实现LED输出不同通道之间的良好匹配。 这些LED驱动器还集成了短路、欠压和热保护，以保证更强健的的解决方案。
FAN5624 采用极小尺寸的 10 引脚 UMLP 封装。

  • TBA
  • • 线性灌电流 LED 驱动器支持 4 个 LED 输出• 每个LED输出的灌电流驱动器：
  • 30mA最大输出电流
  • 50mV压降(15mA IOUT)
  • 通道间匹配高于3%
  • 外部RSET• 用于简单编程的单线式数字控制接口• 关断电流低于1µA• 短路、欠压和热保护• 宽输入电压范围： 2.7V至5.5V• 小尺寸 10 引脚 1.4 x 1.8 x 0.55 mm UMLP 封装
