3A, 2MHz 同步降壓型 DC/DC 轉(zhuǎn)換器

RT8015D為高效率的同步降壓型 DC/DC 轉(zhuǎn)換器，輸入電壓范圍從2.6V至5.5V，可調(diào)的輸出電壓范圍0.8V至5V，輸出電流可達(dá)3A。內(nèi)建的同步低導(dǎo)通阻的功率開關(guān)，增進(jìn)了整體效率并減少了需要外加蕭特基二極管的必要性。切換頻率可由外部電阻進(jìn)行設(shè)計(jì)或由外部時(shí)序訊號進(jìn)行同步操作。藉由近100%占空比的操作提供了低壓差轉(zhuǎn)換的應(yīng)用可有效延長掌上型裝置的電池使用壽命。RT8015D的電流模式架構(gòu)與外部的補(bǔ)償機(jī)制可因應(yīng)大范圍的輸出電容與負(fù)載變化的瞬時(shí)響應(yīng)進(jìn)行優(yōu)化的補(bǔ)償。RT8015D強(qiáng)制操作在PWM的連續(xù)導(dǎo)通模式，大幅降低電壓紋波值與RF干擾所造成的噪聲。藉由近100%占空比的操作提 ? 效率高達(dá) 95%\n? 可控制操作頻率范圍: 300kHz至2MHz\n? 0.8V的參考電壓允許低電壓輸出\n? 近100%的占空比操作允許輸出低壓降轉(zhuǎn)換\n? 符合RoHS規(guī)范與無鹵特性;
