RT6160D 是一款高效率、单电感且采用先进恒定导通时间（ACOT<sup>®</sup>）架构的单芯片同步升降压转换器，可在 2.2V 至 5.5V 的输入范围内提供高达 3A 的输出电流。它能够良好调节可数字编程的输出电压，范围为 2.025V 至 5.2V，使其适用于广泛的输入电源应用，无论输入电压是低于、高于，甚至等于输出电压皆可。ACOT<sup>®</sup> 控制架构具备出色的输入电压 / 负载瞬态响应、降压与升压模式之间的无缝转换，并且无需复杂的外部补偿，即可搭配小型陶瓷输出电容提供稳定运行。RT6160D 配备 I<sup>2</sup>C 接口，可实现可编程输出电压、超声波模式控制、软启动转换速率调整，以及器件状态监测。目标输出电压也可通过外部 VSEL 引脚切换，以执行动态电压调节（DVS），且 DVS 的上升转换速率与斜坡模式也可通过设置相关寄存器进行配置。RT6160D 采用自动 PFM 模式运行，并具备典型值为 2μA 的低静态电流设计，可在轻载运行期间保持高效率。在较高负载下，该器件会自动切换至 2.2MHz 固定频率控制，搭配小型封装滤波元件即可轻松平滑开关纹波电压。此外，集成式低 R<sub>DS(ON)</sub> 功率 MOSFET 在重载条件下具备优异效率。在关断模式下，供电电流典型值为 0.1μA，有助于有效降低功耗。若需要固定频率，可禁用 PFM 模式。RT6160D 采用小型 WL-CSP-15B 1.4x2.3（BSC）封装。建议结温范围为 −40°C 至 125°C，环境温度范围为 −40°C 至 85°C。
