集成 I2C 的 4 路、80V WLED 升压控制器

MP3385A 是一款集成 4 个调节电流通道的升压控制器，用于驱动大中型 LCD 面板背光应用的 WLED 阵列。MP3385A 使用峰值电流模式和 PWM 控制架构来实施系统环路调压。MP3385A 驱动外部 MOSFET，以从 4.5V 至 33V 输入电源升高输出电压。MP3385A 采用 I2C 数字接口来灵活设置操作和保护模式，包括调光模式、调光电流和调光比、OCP、OVP、LED 短路保护阈值和开关频率。为了便于应用使用和在板上调试，MP3385A 在启动期间自动检测和禁用未使用的 LED 字符串，以避免将输出充电到 OVP 阈值。MP3385A 在每个灯串之间可实现 1.8&# • 4 串、每串最大 300mA 的 WLED 控制器\n• 输入电压范围：4.5V - 33V\n• 每串 80V ABS 额定电压\n• 每串的电流匹配精度为 1.8%\n• 启动期间未用通道自动检测功能\n• 100kHz-900kHz 可编程开关频率\n• 可通过 I2C 接口选择多种调光模式\n• O 直接 PWM 调光模式\n• O 通过 I2C 实现内部固定 23kHz PWM 调光模式\n• O 通过输入脉冲实现模拟调光模式\n• O 通过 I2C 实现内部模拟调光模式\n• O 通过输入脉冲实现混合调光模式\n• O 通过 I2C 实现内部混合调光模式\n• 2
