illustrate

该LM3555是一个2 MHz的固定频率，电流模式同步升压转换器，驱动器或单个Flash在500 mA或两个系列LED闪光灯LED在400毫安。 高电压电流源允许LED终止与GND平面省去了额外回报追溯至IC的需求。

双模式控制接口，用户可以配置一个通用使用两个控制或I使能引脚接口LM3555 2 彗星允许更高级别的控制。 这两个接口允许访问指标，辅助灯和闪光灯模式。 专用频闪引脚提供的直接接口来触发闪光灯事件，而外部火炬引脚提供了一个有利的在一个恒定的电流模式的LED额外的方法。

该LM3555可以自适应规模最大闪光级别传递到LED /时基LED闪光灯的配置，无论是单个LED或两个串联的LED。

八保护功能上，从过电压保护，打破电感检测LM3555提供。 该LM3555有四个可选择的电感电流限制，以帮助用户选择一个电感器，它是为设计合适的。
