          RT8089A

          3A, 1MHz, Synchronous Step-Down Converter

          General Description The RT8089A is a high efficiency synchronous, step-down DC/DC converter. Its input voltage ranges from 2.7V to 5.5V that provides an adjustable regulated output voltage from 0.6V to VIN while delivering up to 3A of output current. The internal synchronous low On-resistance pow

          RT8089A

          3A, 1MHz 同步降壓型 DC/DC 轉(zhuǎn)換器

          RT8089A為高效率的同步降壓型DC/DC轉(zhuǎn)換器,輸入電壓范圍為2.7V至5.5V,可調(diào)輸出電壓為0.6V至VIN ,輸出電流可達(dá)3A。由于內(nèi)建同步低導(dǎo)通阻開關(guān)可增加效率并不需外加蕭特基二極管。內(nèi)部切換頻率恒定于1MHz。100%的工作周期提供了低壓降操作,并且延長電池的壽命。由于具有內(nèi)部補(bǔ)償機(jī)制的電流模式恒定導(dǎo)通時(shí)間(CMCOT)操作,可允許系統(tǒng)在大范圍的負(fù)載變動(dòng)、輸出電容變化的操作條件下仍有優(yōu)良的瞬時(shí)響應(yīng)特性。RT8089A支持WDFN-10L 3x3封裝。 · 效率高達(dá)95%\n· 輕載時(shí)高效率\n· 低RDS(ON)開關(guān): 69mΩ/49mΩ \n· 恒定頻率:1MHz\n· 不需外加蕭特基二極管\n· 低壓降操作:100%工作周期\n· 過電流保護(hù)\n· 欠電壓保護(hù) \n· 過熱關(guān)機(jī)保護(hù)\n· 符合RoHS規(guī)范與無鹵特性;
