多相DC/DC控制器突破精度和带宽的限制

LTC3811是一款多功能、高效同步升压控制器，适于低电压、大电流供电的应用。±0.5%的输出电压精度和远程检测差分放大器代表了DC/DC转换器的新标志。该器件易于实现单或双路输出，采用Linear公司的PolyPhase电流分配结构。低的在线时间和固定的频率峰值电流使其成为电源保护的理想选择。MultiphaseDC/DCControllerPushesAccuracyandBandwidthLimitsDesignNote434TickHoukIntroductionInadditiontohighaccuracy,theLTC3811’slowmini-Speedandaccuracydon’talwaysgohand-in-handmumon-time(typically65ns)allowsuserstoconvertainDC/DCconvertersystems―thatis,untilnow.The12Vinputtoa1VoutputatswitchingfrequenciesuptoLTC3811isadualoutput,xedfrequencycurrentmode750kHz,optimizingloadtransientresponseandreducingDC/DCswitchingregulatorcontrollerdesignedforoneofthesoluti
