RT4505 是一款最高开关频率可达 4MHz 的同步升压转换器，并集成一组可提供 1.5A 恒流输出的高电流白光 LED 驱动器。其高端电流源架构支持 LED 阴极接地工作方式，可提供最高 1.5A 的闪光电流。自适应调节机制可确保电流源保持稳定调节状态，同时实现最佳转换效率。 RT4505 通过兼容 I²C 的接口进行控制。产品具备硬件闪光使能（STROBE）功能，可通过逻辑信号直接触发闪光脉冲；同时提供 TX 输入信号，可在射频功率放大器（RF PA）工作或其他高电流负载情况下，将闪光电流切换至较低电流模式，以实现系统同步控制。 最高 4MHz 的开关频率、过压保护功能以及可调式电流限制设置，可搭配体积小巧、低高度的电感和陶瓷电容使用，进一步缩小系统尺寸。 RT4505 采用 WL-CSP-9B（1.3mm × 1.37mm，BSC）封装，工作温度范围为 -40°C 至 85°C。
