3A, 23V, 1.2MHz 同步降壓型 DC/DC 轉(zhuǎn)換器

RT8283B為高效率、單晶同步降壓型DC/ DC轉(zhuǎn)換器，在4.5V至23V的輸入電源范圍可提供最高為3A的輸出電流。RT8283B采用電流模式架構(gòu)和外部補(bǔ)償方式，可優(yōu)化瞬時(shí)響應(yīng)的特性。逐周期的電流限制保護(hù)組件免受輸出短路影響；軟啟動(dòng)功能可在啟動(dòng)過(guò)程中防止了輸入電流過(guò)沖。RT8283B同時(shí)提供輸出欠壓保護(hù)和過(guò)溫保護(hù)。低電流消耗(<3μA)之電源關(guān)機(jī)模式會(huì)將輸出關(guān)閉，有助于電池供電系統(tǒng)的電源管理。RT8283B提供SOP-8 (裸露焊盤(pán))封裝。 ? ±1.5% 高精準(zhǔn)度參考電壓\n? 3A輸出電流\n? 電流模式控制\n? 可調(diào)輸出電壓范圍：0.8V至20V\n? 可采用低ESR的陶瓷電容做為輸出電容\n? 逐周期的電流限制機(jī)制\n? 輸出欠電壓保護(hù)\n? 符合RoHS規(guī)范與無(wú)鹵特性;
