43V, 异步升压 LED 驱动器

RT8511A 是可以驱动多达10只串联连接的 WLED 的驱动 IC , 内部包含一个集成了 43V/1.2A 功率开关的电流模式 Boost 转换器，工作频率为恒定的 1MHz，可以使用在 2.7V~24V 输入电压范围内。\n\n其输出电流可以通过一个外部电阻进行设定，回馈电压被调整至 200mV （典型值）。在操作期间，LED 电流可由一个 PWM 输入信号进行控制，该信号的占空比决定了回馈系统的参考电压的大小。\n\n为了实现亮度调整， RT8511A 能够实现 LED 电流的稳定控制，因而在输出电容上不会出现音频噪声。RT8511A 有一个可程序设计的过压保护端子，用于避免在 LE • 宽输入电压范围：2.7V~24V\n• 直接 PWM 调光控制，信号频率范围：100Hz~100kHz\n• 200mV 参考电压\n• 可程序设计过压保护\n• 过流保护\n• 符合 RoHS 规范，不含卤素;

9- and 11-Channel, Muxed Input LCD Reference Drivers

GENERAL DESCRIPTION The AD8509 and AD8511 are 9-channel and 11-channel LCD reference buffers, respectively, designed to drive 64 gray scale column drivers. Each buffer has an A/B input to select between two voltages for LCD displays. These buffers drive the resistor ladders of LCD column drivers
