4通道 150mA 恒流 LED 驱动器

RT8300 是4通道 150mA 恒流吸入式 LED 驱动器，4个通道间具有很好的电流一致性并容许很宽的 VF 变化范围。 RT8300 的4个通道的电流差异在 3% 以内，在不同芯片之间的误差也是如此。没个通道的电流可以通过一个外部电阻（ R_ISET )进行调整，其范围在 5mA~150mA 之间。LED 的亮度还可以通过在 PWMI 引脚施加占空比在 0%~100% 的 PWM 信号进行调节。 RT8300 具有动态余量控制（ DHC ）功能，它能生成回馈信号送给 DC/DC 控制回路调节其供给 RT8300 的电压。它还具有 LED 开路、 • 4个恒流输出通道\n• 低压差：600mV@120mA\n• 动态余量控制（ DHC ）功能\n• OTP、LED 开路/短路故障检测、指示\n• 符合 RoHS 规范，不含卤素;
