RTQ7883 是一款高度集成的 USB Type-C Power Delivery（USB PD）控制器，内置双开关（2-Switch）PWM 降压转换器，可提供最高 3A 输出电流，并支持高达 99% 占空比运行，以实现低压差（Low Dropout）输出能力。 该产品内置 ARM Cortex-M0 微控制器（MCU），可执行通信协议处理、PWM 转换器智能控制、基于固件的保护机制以及定制化功能等多项任务。 RTQ7883 具备硬件保护功能，包括电感峰值电流限制（Inductor Peak Current Limit）、VBUS 过压保护（VBUS OVP）以及输出欠压保护（VO UVP）。这些保护机制可提供更快速的响应速度，并且即使 MCU 尚未启动时仍可正常工作，进一步提升系统安全性与可靠性。 RTQ7883 仅需少量外围元件及简单 PCB 布局，即可为 USB PD 电源提供端（USB PD Provider）应用提供完整且高效的解决方案。 建议结温范围为 -40°C 至 150°C，环境温度范围为 -40°C 至 125°C。
