高功率密度通用型3相PWM控制器

RT8800A是一通用型多相同步降壓轉(zhuǎn)換器，適合高功率密度應(yīng)用，可在自動(dòng)的錯(cuò)相設(shè)定中執(zhí)行2或3同步降壓轉(zhuǎn)換階段。此多相架構(gòu)讓供電應(yīng)用在高輸出電流中，可維持低功耗和輸入、輸出電容的低應(yīng)力。輸出電壓透過PI接腳的外部參考電壓精確調(diào)節(jié)，當(dāng)配合DAC發(fā)生器RT9401A/B，即可提供Intel^? VRD10.x 或AMD^? K8標(biāo)準(zhǔn)輸出電壓。RT8800A采用創(chuàng)新的時(shí)分 DCR 電流檢測(cè)技術(shù)實(shí)施電流平衡操作、降壓調(diào)整和過流保護(hù)，并用檢測(cè)電流的通用GM放大器消除偏移誤差及GM間的線性不一致性。由于現(xiàn)代的主板普遍使用了低于毫奧姆級(jí)的電感，小的偏移和線性不一致性即 ?5V 供電\n?以外部參考電壓調(diào)節(jié)的輸出電壓\n?使用 DCR 電流檢測(cè)技術(shù)進(jìn)行功率級(jí)熱平衡\n?內(nèi)部軟啟動(dòng)\n?過壓保護(hù)\n?電源良好指示\n?符合 RoHS 規(guī)范且完全無鉛;
