高功率密度 2/3/4/5 相 PWM 控制器

RT8802A 是2/3/4/5相同步 Buck 控制器，專(zhuān)門(mén)為 Intel^? / AMD 下一代微處理器供電而設(shè)計(jì)。它使用了內(nèi)建的8位 DAC 用于轉(zhuǎn)換來(lái)自微處理器的 VID 編碼為輸出電壓，該 VID 編碼與輸出電壓之間的對(duì)應(yīng)關(guān)系與 Intel^? VRD10.x 和 VRD11 內(nèi)核電源所定義的數(shù)據(jù)是一致的，其級(jí)間電壓差為 6.25mV ，精度為0.5%。RT8802A 采用了創(chuàng)新的時(shí)分 DCR 電流檢測(cè)技術(shù)對(duì)各相電流進(jìn)行檢測(cè)并實(shí)施電流平衡操作、負(fù)載線設(shè)定和過(guò)流保護(hù)，其中采用了公用放大器來(lái)檢測(cè)各項(xiàng)電流，使得采用多個(gè)放大器的傳統(tǒng)電流檢測(cè)方 ? 5V 供電\n? 8位 VID 接口，支持 Intel VRD11/VRD10.x 和 AMD K8, K8_M2 CPU\n? 精確的內(nèi)核電壓調(diào)整\n? 可調(diào)軟起動(dòng)\n? 可調(diào)工作頻率，每相典型頻率為 300kHz\n? 40引腳 VQFN 封裝\n? 符合 RoHS 規(guī)范，完全無(wú)鉛;
