RT8890是雙輸出3+2相PWM控制器，具有3個整合MOSFET柵極驅動器和單個SVID介面，用於CPU和GPU內核供電。本產品符合英特爾VR12 / IMVP7脈衝寬度調變規範。 RT8890採用立錡專有的G-NAVP™ (Green-Native AVP) 技術，這是一種由固定導通時間控制模式中的有限直流增益補償器得到的。G-NAVP™使該部分成為一種易於設置的PWM控制器，可滿足所有英特爾移動CPU / GPU AVP (動態電壓定位) 要求。RT8890使用SVID介面控制內部8位DAC進行輸出電壓編程。內置高精準度DAC將VID代碼轉換為0V至1.52V的參考電壓，並具有5mV步階電壓。控制器的系統精準度達到0.8%。RT8890的每個輸出通道都可以在多相連續導通模式或單相DEM (diode emulation mode) 模式下工作，在不同的負載條件下達到最大90%的效率。可以選擇droop功能 (負載線)，並通過設置誤差放大器的直流增益輕鬆編程負載線。通過適當的補償，負載瞬態響應可以達到優化的AVP性能。輸出電壓轉換的轉換速率通過SVID介面編程。 RT8890支援電感DCR和感測電阻電流檢測、為IMVP7 CPU和GPU內核提供電源良好指示、電流監視器、熱監視器和熱節流輸出信號。此外，還提供完整的故障保護功能，包括過壓，欠壓，負電壓，過流，熱關斷和欠壓鎖定。
