●简介
■SGM3785是与手机摄像头模块或数码相机一起使用的高功率闪光灯LED的理想电源解决方案。它是一个高度集成的升压DC/DC转换器，具有非常高的开关频率，固定在2MHz，为便携式闪光灯提供了一个非常小的整体解决方案。SGM3785具有独立的闪存模式和电影/火炬模式启用引脚，可实现最大的灵活性。闪光模式通常与660ms定时器控制一起使用，以产生高强度的闪光。闪光灯模式和电影/火炬模式的最大LED电流分别由外部电阻器编程，使闪光灯LED解决方案易于控制。闪光模式和电影/火炬模式下的实际LED电流可以通过ENM引脚上的外部PWM信号进行编程。

■两个LED输出散热器可以在外部短路在一起，以获得更高功率的单闪LED，高达1.5A的连续LED电流。热调节集成在Flash模式中，以限制IC的温度并持续提供最大允许输出电流。

■SGM3785内置各种保护功能，包括逐周期输入限流保护、输出过电压保护、LED故障（开路或短路）保护和热关机保护。停机时的泄漏电流小于1uA。

■SGM3785有绿色TDFN-3×2-14L封装。它在-40℃至+85℃的环境温度范围内运行。

●主要功能：

■输入电压范围：3V至5V
■最高1.5A LED总电流
■最高90%效率
■双闪LED输出
■微型电感器：1.0μH
■2MHz升压转换器
■独立的闪光模式启用和电影/火炬模式启用控制引脚
■闪光电流和电影/炬电流可通过ENM引脚上的PWM信号编程
■独立电阻器分别设置闪光电流和视频/火炬电流

■670ms闪光定时器控制
■ENM和ENF引脚上的360kΩ下拉电阻器
■保护功能
▲输出过电压保护
▲LED开路或短路保护
▲逐周期电流限制
■小于1μA关断电流
■绿色TDFN-3×2-14L封装
■温度范围：-40℃至+85℃
