雙路4.5V至18V輸入, 5A同步Buck轉(zhuǎn)換器

RT2825是集成了兩組5A同步Buck轉(zhuǎn)換器的電源IC，工作電壓范圍為4.5V至18V，為電子系統(tǒng)的設(shè)計(jì)者提供了優(yōu)化的電源管理方案。\n\nRT2825的兩組轉(zhuǎn)換器均可在5V、9V、12V或15V的系統(tǒng)中應(yīng)用，均集成了功率開關(guān)。它們采用電流模式控制架構(gòu)，瞬態(tài)響應(yīng)特性良好。它們?cè)诠ぷ鬟^程中采用逐周期電流限制方式，可在輸出端出現(xiàn)短路現(xiàn)象時(shí)提供保護(hù)作用。\n\nRT2825的兩組轉(zhuǎn)換器都含有方便進(jìn)行時(shí)序控制的使能控制端，有可接電容的軟起動(dòng)端子對(duì)啟動(dòng)過程進(jìn)行控制，有獨(dú)立的電流限制端子 (RLIMx) 可對(duì)電流限制閾值進(jìn)行調(diào)節(jié)，同時(shí)使電感器的選擇更加安全。透過對(duì)COMP端外接的RC電路參數(shù)的調(diào)整，用戶 ? 輸入電壓范圍：4.5V至18V\n? 可外部引入或用外部電阻調(diào)節(jié)的工作頻率范圍：200kHz至1MHz\n? 電流控制模式，補(bǔ)償電路簡單\n? 過熱保護(hù)\n? 假如LOWP為低電平，輕載時(shí)進(jìn)入不連續(xù)操作模式\n? 符合RoHS規(guī)范，完全無鉛;
