RTQ5162 是一款整合式电源管理 IC，专为 DDR5 SODIMM、UDIMM、CSODIMM 与 CUDIMM 应用而设计。此元件提供三个降压转换器 (SWA、SWB 与 SWC) 以及两个 LDO (VLDO_1.0V 与 VLDO_1.8V)。电压稳压器 SWA 与 SWB 可在单相或双相模式下运作。此外，RTQ5162 支援可选介面 (I<sup>2</sup>C 或 I3C Basic)，以因应各种应用环境。其内嵌完整保护机制，以确保安全的电源分配，并具备将故障事件记录于暂存器中，以及透过 PWR_GOOD 与 GSI_n 开汲极指示器发出讯号的能力。RTQ5162 采用 WQFN-28L 3x4 (FC) 封装。建议接面温度范围为 −40°C 至 125°C。
