LTC3850

雙通道路、兩相同步降壓型開關(guān)控制器

LTC3850是一款高性能雙通道同步降壓開關(guān)穩(wěn)壓器控制器，可驅(qū)動N溝道功率MOSFET級。恒頻電流模式架構(gòu)支持高達780kHz的可鎖相頻率。通過使兩個控制器輸出級異相操作，可較大限度地降低功耗和電源噪聲。\n\n OPTI-LOOP?補償可以在較大的輸出電容和ESR值范圍內(nèi)優(yōu)化瞬態(tài)響應。LTC3850集成了0.8V精密基準電壓源和電源良好輸出指示器。4V至24V（最大28V/LTC3850I為30V）的寬輸入電源范圍涵蓋大多數(shù)電池化學和中間總線電壓。\n\n 每個控制器的獨立TK/SS引腳使輸出電壓在啟動期間升高。電流折返在短路情況下會限制MOSFET散熱性能。MODE/P; ? 雙通道180°相位控制器可降低所需的輸入電容和電源引起的噪聲\n\n? 高效率：高達95%\n\n? RSENSE或DCR電流檢測\n\n? 0.8V輸出電壓精度：±1%\n\n? 可鎖相的固定頻率：250kHz至780kHz\n\n? 支持預偏置輸出;
