RTQ5162 是一款整合式電源管理 IC,專為 DDR5 SODIMM、UDIMM、CSODIMM 與 CUDIMM 應用而設計。此元件提供三個降壓轉換器 (SWA、SWB 與 SWC) 以及兩個 LDO (VLDO_1.0V 與 VLDO_1.8V)。電壓穩壓器 SWA 與 SWB 可在單相或雙相模式下運作。此外,RTQ5162 支援可選介面 (I<sup>2</sup>C 或 I3C Basic),以因應各種應用環境。其內嵌完整保護機制,以確保安全的電源分配,並具備將故障事件記錄於暫存器中,以及透過 PWR_GOOD 與 GSI_n 開汲極指示器發出訊號的能力。RTQ5162 採用 WQFN-28L 3x4 (FC) 封裝。建議接面溫度範圍為 −40°C 至 125°C。
