PWM-VID輸入多相Buck PWM控制器

RT8845B是針對(duì)高性能圖像處理器和計(jì)算機(jī)應(yīng)用進(jìn)行了優(yōu)化處理的4/3/2/1相同步Buck PWM控制器，采用了立锜特有的基于有限直流增益誤差放大器的電流模式控制技術(shù)的G-NAVP^TM (Green Native AVP) 控制架構(gòu)，工作頻率可隨VID輸入、負(fù)載和輸入電壓而變，即使在CCM模式下工作也可有效提升轉(zhuǎn)換效率，并另有與G-NAVP^TM架構(gòu)結(jié)合在一起的CCRCOT (Constant Current Ripple COT，固定電流紋波COT) 技術(shù)可在整個(gè)輸入、輸出范圍內(nèi)提供超低的輸出電壓紋波水平。此外，它還具有完善的故障保護(hù)功能，如過壓保 ? 多相PWM控制器\n? 支持1.8V PWM-VID接口\n? 動(dòng)態(tài)PWM-VID電壓控制方式\n? 內(nèi)/外軟起動(dòng)控制\n? 工作頻率可調(diào)\n? 支持超低輸出電壓作為待機(jī)電壓\n?
