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換器，適合高功率密度應用，可在自動的錯相設定中執(zhí)行2或3同步降壓轉換階段。此多相架構讓供電應用在高輸出電流中，可維持低功耗和輸入、輸出電容的低應力。輸出電壓透過PI接腳的外部參考電壓精確調節(jié)，當配合DAC發(fā)生器RT9401A/B，即可提供Intel^? VRD10.x 或AMD^? K8標準輸出電壓。RT8800A采用創(chuàng)新的時分 DCR 電流檢測技術實施電流平衡操作、降壓調整和過流保護，并用檢測電流的通用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?以外部參考電壓調節(jié)的輸出電壓\n?使用 DCR 電流檢測技術進行功率級熱平衡\n?內部軟啟動\n?過壓保護\n?電源良好指示\n?符合 RoHS 規(guī)范且完全無鉛;
