RT8207 | DDRII/DDRIII 內存電源供應控制器 RT8207 為 DDR II/DDRIII 內存系統(tǒng)提供了完整的電源供應，其中集成了一個同步 Buck 架構的 PWM 控制器和一個具有 3A 電流吐納能力的追蹤型線性穩(wěn)壓器，還有一個經過緩沖處理的低噪聲參考電壓源。其中的 PWM 控制器為筆記本電腦的 RAM 內存部分提供了將電池高電壓轉換為低壓供電的高效率方案，具有優(yōu)異的瞬態(tài)響應能力和極高的輸出電壓精度。它所采用的固定導通時間 PWM 控制架構能很容易地面對很寬的輸入/輸出電壓比率范圍，能在維持相對穩(wěn)定的工作頻率情況下以快達 100ns 的實時響應能力對負載瞬變做出回應。RT8207 拋棄了傳統(tǒng)電流模式 PWM 控制器中使用電阻進行電流檢 ?PWM 控制器\n?3A 線性穩(wěn)壓器（ VTT ），帶緩沖的參考電壓（ VTTREF ）\n?符合 RoHS 規(guī)范，不含鹵素; | Richtek 立锜科技 | Richtek | |
