RT6585C 是一款双通道降压控制器，可为电池供电系统产生供电电压。其包含两个可在 2V 至 5.5V 之间调节的脉冲宽度调制 (PWM) 控制器，以及两个固定 5V/3.3V 线性稳压器。每个线性稳压器可提供高达 100mA 的输出电流，且 3.3V 线性稳压器在 35mA 以下可提供 1% 精度。RT6585C 提供一个模式选择引脚 SKIPSEL，可选择二极管仿真模式 (DEM) 或音频跳脉冲模式 (ASM)。其他特性包括板载上电时序、电源良好输出、内部软启动，以及可在关断期间防止负电压的软放电输出。<br />恒定电流纹波 PWM 控制架构无需检测电阻即可运行，并可对负载瞬态提供 100ns 响应。为了最大化电源效率，RT6585C 会在轻载应用中自动切换至二极管仿真模式。RT6585C 采用 WQFN-20L 3x3 封装。建议结温范围为 −40°C 至 125°C。
