RT8848C 是一款 8/7/6/5/4/3/2/1 多相同步降壓控制器,針對高效能繪圖微處理器進行最佳化,並透過 PWM-VID 介面支援 nVidia OVR4i+ 規範。RT8848C 採用 AC G-NAVP<sup>TM</sup> (Green Native AVP),這是立錡專有的拓撲,由內部 GM 放大器的有限 DC 增益搭配電流模式控制所衍生。透過採用 AC G-NAVP<sup>TM</sup> 拓撲,RT8848C 的工作頻率會隨 VID、負載與輸入電壓而變化,即使在 CCM 下亦可進一步提升效率。此外,對於電流感測應用,RT8848C 可支援來自電感的傳統 DCR 網路電流感測,或可直接提供電流監測訊號 (IMON) 的智慧功率級 (SPS)。<br /><br />RT8848C 具備外部參考輸入與 PWM-VID 動態輸出電壓控制,其中輸出電壓會被調節並追蹤外部輸入參考電壓。RT8848C 可透過 PINSETx 腳位設定內部 RAMP 振幅,以最佳化穩定性與負載暫態效能。RT8848C 亦提供完整的故障保護功能,包括過壓保護 (OVP)、欠壓保護 (UVP)、通道過電流限制 (CH_OC)、總輸出電流保護 (SOC) 與過溫保護 (OTP)。建議接面溫度為 −40°C 至 125°C。
