800mA、2MHz、PWM DC-DC降壓型轉(zhuǎn)換器，帶有復(fù)位

MAX1572是一款固定頻率、同步降壓型DC-DC轉(zhuǎn)換器，能夠?yàn)镻CB面積受限制、需要高轉(zhuǎn)換效率的便攜設(shè)備中的低電壓微處理/DSP核提供電源。經(jīng)過優(yōu)化的特性可在較寬的負(fù)載范圍內(nèi)保持高效，具有小尺寸外部元件、低輸出紋波和優(yōu)異的瞬態(tài)響應(yīng)特性。輸入電壓范圍2.6V至5.5V，輸出電壓可由內(nèi)部固定在0.75V至2.5V，每級(jí)增量為50mV，保證輸出電流達(dá)800mA。2MHz的高開關(guān)頻率允許選用小巧的低成本電容和小尺寸電感，節(jié)省功耗的脈沖群模式能夠在輕載下使靜態(tài)電流減小至48μA (典型值)。為了降低噪聲和RF干擾，轉(zhuǎn)換器可以配置為強(qiáng)制PWM工作模式。\nMAX1572內(nèi)部具有一個(gè)低導(dǎo)通電阻的MOSFE ? 效率高達(dá)97% \n? 2MHz PWM開關(guān)頻率 \n? 保證800mA輸出電流 \n? 48μA低靜態(tài)電流 \n? 省電模式：脈沖群、脈沖跳頻、強(qiáng)制PWM模式 \n? 預(yù)置0.75V至2.5V輸出范圍(50mV輸出增量) \n? 電壓定位負(fù)載瞬變 \n? 5mVP-P輸出紋波 \n? 微型2.2μH電感 \n? 10μF陶瓷輸出電容 \n? 0.1μA低關(guān)斷電流 \n? 無需外部肖特基二極管 \n? 零浪涌電流軟啟動(dòng) \n? 170ms (最小) /RESET輸出 \n? 小型12引腳、4mm x 4mm薄型QFN封裝;
