雙通道高效率PWM降壓型 DC/DC 轉(zhuǎn)換器

RT8020E 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。RT8020E適用于由單一鋰電池供電的可攜式電子裝置，例如移動電話、PDA與掌上型裝置。\n\nRT8020E 具備兩種操作模式:PWM/低壓降 自動切換模式以及關(guān)機(jī)模式。操作于PWM模式時可藉由內(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\nRT8020E當(dāng)PWM操作時無法連續(xù)導(dǎo)通上端PMOS時，進(jìn)入低壓降模式。當(dāng)EN腳位為低電位時，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 ? 2.5V 至5.5V 輸入范圍\n? 1A 輸出電流\n? 不需外加蕭特基二極管\n? 1.5MHz 固定頻率的PWM操作\n? 符合RoHS規(guī)范與無鹵特性;
