性能增強(qiáng)、高效率并具備出色峰值功率特性的離線式開關(guān)IC

PeakSwitch用來滿足對(duì)峰值與連續(xù)輸出功率的比例要求很高的應(yīng)用。在峰值功率負(fù)載情況下工作在很高的開關(guān)頻率上及良好的負(fù)載瞬態(tài)響應(yīng)降低了系統(tǒng)成本，同時(shí)減少了元件數(shù)目及尺寸。PeakSwitch將一個(gè)700 V的功率MOSFET、振蕩器、用于啟動(dòng)的高壓開關(guān)電流源、限流電路及熱關(guān)斷保護(hù)電路集成在一個(gè)單片器件內(nèi)。另外，該器件還具備自動(dòng)重啟動(dòng)、輸入欠電壓檢測及頻率調(diào)制特性。創(chuàng)新的設(shè)計(jì)減低了開／關(guān)控制方式中音頻范圍的頻率分量，既使使用標(biāo)準(zhǔn)浸漬的變壓器，也聽不到音頻噪音。 EcoSmart ? — 極高效率\r\n? 在輸入功率為1 W時(shí)(交流高電壓)，待機(jī)輸出功率≥ 0.6W\r\n? 在輸入功率為3 W時(shí)(交流高電壓)，睡眠模式的輸出功率≥ 2.4 W\r\n? 在 265 VAC 輸入情況下，空載功率消耗< 200 mW\r\n? 超出加州能源委員會(huì)(CEC)、能源之星及歐盟節(jié)能標(biāo)準(zhǔn)的要求\r\n\r\nPeakSwitch的產(chǎn)品特色降低了系統(tǒng)成本\r\n? 峰值功率可達(dá)到最大連續(xù)輸出功率的三倍\r\n? 在提供值輸出功率時(shí)，器件工作在277 kHz，極大地降低了變壓器尺寸\r\n? 可編程的智能AC電壓檢測電路提供了短路、過載及開環(huán)故障鎖存關(guān)斷保護(hù)，防止;
