RT3607CJ 是一款符合 IMVP8 規範的 CPU 電源控制器,包含兩組電壓軌:4/3/2/1 相同步降壓控制器 CORE VR,以及 3/2/1 相同步降壓控制器 AXG VR。RT3607CJ 採用 G-NAVP<sup>TM </sup>(Green Native AVP),這是 Richtek 專有的拓撲架構,由具有限 DC 增益的 EA 放大器結合電流模式控制所衍生,可輕鬆設定 droop,以滿足所有 Intel CPU 對 AVP(Adaptive Voltage Positioning)的要求。基於 G-NAVP<sup>TM</sup> 拓撲,RT3607CJ 亦具備快速反應機制,可在負載暫態期間優化 AVP 效能。RT3607CJ 支援具多種操作狀態的模式轉換功能。RT3607CJ 內建序列 VID(SVID)介面,可與符合 Intel IMVP8 規範的 CPU 通訊。RT3607CJ 支援即時 VID 調整功能,並提供三種不同的轉換速率:Fast、Slow 與 Decay。透過 G-NAVP<sup>TM</sup> 拓撲,RT3607CJ 的操作頻率會隨 VID、負載與輸入電壓而變化,即使在 CCM 下也能進一步提升效率。此外,採用 CCRCOT(Constant Current Ripple COT)技術的 G-NAVP<sup>TM</sup> 可在整個輸入/輸出範圍內提供優異的輸出電壓漣波表現。內建高精度 DAC 可將 0.25V 至 1.52V 範圍的 SVID 碼以每階 5mV 進行轉換。RT3607CJ 整合高精度 ADC,用於平台設定功能,例如快速反應觸發位準或過電流位準。此外,該設定功能也支援這兩組電壓軌的位址交換。RT3607CJ 提供 VR ready 輸出訊號。它亦具備完整的故障保護功能,包括過電壓(OV)、負電壓(NV)、過電流(OC)及欠電壓鎖定(UVLO)。RT3607CJ 採用 WQFN-56L 6x6 小尺寸封裝。
