控制器，準(zhǔn)諧振，電流模式，低待機(jī)耗量，帶 PFC 關(guān)斷

NCP1382 采用 SO-14 封裝，包括構(gòu)建堅(jiān)固高能效的準(zhǔn)諧振 (QR) 開(kāi)關(guān)電源所需的一切功能。通過(guò)前端功率因數(shù)修正電路供電時(shí)，NCP1382 會(huì)在低輸出負(fù)載條件下自動(dòng)斷開(kāi) PFC 控制器（帶可調(diào)節(jié)級(jí)），因此改善了待機(jī)功耗性能。這尤其適用于中高功率離線應(yīng)用，如筆記本電腦適配器。當(dāng)電流設(shè)置點(diǎn)降至某個(gè)給定值以下，如輸出功率需求消失時(shí)，該集成電路將進(jìn)入所謂的跳過(guò)周期模式，在輕負(fù)載下提供卓越能效。因?yàn)榘l(fā)生此情況時(shí)具有可調(diào)節(jié)低峰值電流和專(zhuān)屬的軟跳過(guò)技術(shù)，所以不會(huì)產(chǎn)生噪聲。跳過(guò)周期還能夠輕松選擇發(fā)生折回和待機(jī)的最大開(kāi)關(guān)頻率。NCP1382 還具有若干有效保護(hù)選項(xiàng)，如 a)獨(dú)立于輔助電壓的短路過(guò)載檢測(cè) ? Current-Mode Quasi-Resonant Operation\n? Adjustable Line Over Power Protection\n? Extremly Low Startup Current of 15 uA Maximum\n? Soft-Skip Cycle Capability at Adjustable Peak Currents\n?
