RTQ5132 是一款整合式电源管理 IC（PMIC），适用于一般 DDR5 SODIMM 与 UDIMM 应用。此元件内建三组降压转换器（Buck Converter，SWA、SWB 与 SWC）以及两组 LDO 稳压器（VLDO_1.0V 与 VLDO_1.8V），可提供 DDR5 模组所需的多组电源轨。 此外，RTQ5132 支援可选择的通讯介面（I²C 或 I3C Basic），可因应不同应用环境及系统需求。 本产品内建完整的保护机制，以确保电源分配安全可靠。当发生异常状况时，相关故障事件可记录于内部暂存器中，并透过 PWR_GOOD 与 GSI_n 开漏（Open-Drain）讯号输出进行状态指示。 RTQ5132 采用 WQFN-28L 3mm × 4mm（FC）封装。建议接面温度范围为 -10°C 至 125°C，环境温度范围为 0°C 至 85°C。
