具有超低噪聲基準(zhǔn)電壓源的18V、2A降壓型Silent Switcher 3

LT8622S/LT8624S 同步降壓型穩(wěn)壓器采用第三代Silent Switcher技術(shù)，并將超低噪聲基準(zhǔn)電壓源與Silent Switcher架構(gòu)相結(jié)合，以實現(xiàn)高效率和出色的寬帶噪聲性能。\n\n 該創(chuàng)新型超低噪聲架構(gòu)在開關(guān)穩(wěn)壓器中提供出色的低頻（0.1Hz至100kHz）輸出噪聲性能。輸出電壓可通過單個電阻編程設(shè)定，在輸出范圍內(nèi)保持單位增益操作，可提供幾乎恒定的輸出噪聲，而不受輸出電壓影響。Silent Switcher架構(gòu)盡可能降低EMI輻射，并在高開關(guān)頻率下提供高效率。\n\n LT8622S/LT8624S非常適合受益于同步開關(guān)穩(wěn)壓器高效率的高電流、噪聲敏感應(yīng) ?
