4MHz、高电流 LED 闪光灯驱动器

LM3565 是一款 4MHz 定频、电流模式同步升压转换器，此转换器被设计成以 930mA 的电流驱动两个串联闪光 LED。 一个高压电流源使得 LED 能够被端接至接地层，从而免除了对于返回至集成电路 (IC) 的额外返回迹线的需要。 一个专用选通脉冲引脚提供了一个直接接口来触发闪光事件，与此同时，一个外部 Torch 引脚提供了一个在恒定电流模式中启用 LED 的额外方法。 LM3565 能够根据测得的输入电压来自适应地提升传送至 LED 的最大闪光电平。 LM3565 上提供从过压保护到输出短路检测的多重保护特性。 LM3565 具有四个可选电感器电流限值，以帮助用户选择一个适合于此设 • 高效同步升压转换器\n• 以高达 930mA 的电流驱动器 2 个串联的 LED\n• 针对硬件使能闪光的外部选通脉冲引脚 \n• 针对硬件使能电筒的外部 Torch 引脚\n• 专用传输中断引脚\n• 针对 LED 电压和输入电压监视的 8 位模数转换器 (ADC)\n• 自动二极管电流回落\n• 闪光和辅助模式中的脉宽调制 (PWM) 控制\n• 故障检测和报告\n• 400kHz I2C 兼容接口\n• 16 焊锡凸点，1.990mm x 1.990mm x 0.6mm 芯片级球栅阵列 (DSBGA) 封装 (YZR0016AAA);
