Dual, 180? Out-of-Phase, 1.4MHz, 750mA Step- Down Regulator with POR and RSI/PFO

General Description The MAX1970/MAX1971/MAX1972 dual-output current-mode PWM buck regulators operate from 2.6V to 5.5V input and deliver a minimum of 750mA on each output. The MAX1970 and MAX1972 operate at a fixed 1.4MHz (MAX1971 operates at 700kHz) to reduce output inductor and capacitor size a

雙路、180°異相、1.4MHz、750mA、降壓型調(diào)節(jié)器，帶有POR和RSI/PFO

MAX1970/MAX1971/MAX1972是雙路輸出電流型PWM buck轉(zhuǎn)換器，工作于2.6V至5.5V的輸入電壓，達到每路至少750mA的輸出電流。MAX1970和MAX1972工作于固定的1.4MHz (MAX1971工作于700kHz)頻率，降低了輸出電感和電容的尺寸和成本。穩(wěn)壓器180°錯相開關工作也降低了輸入電容的尺寸和成本。陶瓷電容可用于輸入和輸出。\n\n 通過外置反饋電阻，輸出電壓可以設定為1.2V至VIN；或?qū)⑤敵?預置為1.8V或3.3V, 輸出2預置1.5V或2.5V。如果某路輸出高于1.2V，則另一路輸出可設定至1V以下的電壓?？紤]負載、線路和溫度等變化 ? 電流模式、1.4MHz固定頻率PWM工作\n? 180°錯相工作減小輸入電容\n? 在整個負載、線路和溫度變化范圍內(nèi)，達到了±1%輸出精確度\n? 保證750mA輸出電流\n? 2.6V至5.5V的輸入電壓\n? 上電復位延遲16.6ms (MAX1970)或175ms (MAX1972和MAX1972)\n? 電源失效輸出(僅MAX1970和MAX1972)\n? 上電復位輸入(僅MAX1971)\n? 工作在xDSL帶外\n? 采用更小元件的超緊湊設計\n? 0.8V至VIN可調(diào)輸出或1.8V/3.3V和1.5V/2.5V的預置輸出\n? 全部采用陶瓷電容\n? 軟啟動減小浪涌;
