雙通道高效率PWM降壓型 DC/DC 轉(zhuǎn)換器

RT8020 為雙通道高效率脈波寬度調(diào)變(PWM)降壓型DC/DC 轉(zhuǎn)換器?？稍趯捿斎敕秶?.5V 至 5.5V輸出1A電流。RT8020適用于由單一鋰電池供電的可攜式電子裝置，例如移動(dòng)電話、PDA與掌上型裝置。\n\nRT8020 具備兩種操作模式:PWM/低壓降 自動(dòng)切換模式以及關(guān)機(jī)模式。操作于PWM模式時(shí)可藉由內(nèi)部具備低R_DS(ON)的同步整流組件大幅的降低導(dǎo)通損耗。并不需外加蕭特基二極管于實(shí)際應(yīng)用中。\n\nRT8020當(dāng)PWM操作時(shí)無法連續(xù)導(dǎo)通上端PMOS時(shí)，進(jìn)入低壓降模式。當(dāng)EN腳位為低電位時(shí)，進(jìn)入關(guān)機(jī)模式，消耗電流小于0.1μA。\n\n由于操作在固定頻率1 ? 2.5V 至5.5V 輸入范圍\n? 1.2V、1.3V、 1.8V、 2.5V 與 3.3V 的固定/可調(diào) 輸出電壓\n? 效率達(dá)95% \n? 每通道50μA 的靜態(tài)電流\n? 小型的 12-引腳 WDFN 封裝\n? 符合RoHS規(guī)范與100%的引腳無鉛特性\n;
