40V、低IQ、3MHz、兩相同步升壓型控制器

LTC7806是一款高性能、兩相、單輸出、同步升壓轉(zhuǎn)換器控制器，可異相驅(qū)動兩個N通道功率MOSFET級。其恒頻電流模式架構(gòu)支持高達(dá)3MHz的鎖相開關(guān)頻率。與單相等效電路相比，高頻兩相操作降低了輸入和輸出電容要求，并允許使用更小的電感。同步整流可提高效率、降低功耗和散熱要求，從而簡化高功率升壓應(yīng)用。同步直通功能還可以最大限度地降低汽車啟停應(yīng)用中的損耗。\n\n LTC7806在4.5V至40V的寬輸入電源范圍內(nèi)工作。當(dāng)偏離升壓轉(zhuǎn)換器輸出時，LTC7806可在啟動后以低至1V的輸入電源工作。極低的空載靜態(tài)電流可延長電池供電系統(tǒng)的工作運(yùn)行時間。OPTI-LOOP?補(bǔ)償可以在較大的輸出電容和 ? 2 相操作可降低所需的輸入和輸出電容以及電源感應(yīng)噪聲\n\n? 同步運(yùn)行，以實(shí)現(xiàn)最高效率，并減少散熱\n\n? 寬輸入電壓范圍：啟動后，為 4.5V 至 40V，并可在低至 1V 時工作\n\n? 輸出電壓高達(dá) 40V\n\n? 低工作靜態(tài)電流：18μA\n\n?
