Dual, 180째 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

双路、180°异相、1.4MHz、750mA、降压型调节器，带有POR和RSI/PFO

MAX1970/MAX1971/MAX1972是双路输出电流型PWM buck转换器，工作于2.6V至5.5V的输入电压，达到每路至少750mA的输出电流。MAX1970和MAX1972工作于固定的1.4MHz (MAX1971工作于700kHz)频率，降低了输出电感和电容的尺寸和成本。稳压器180°错相开关工作也降低了输入电容的尺寸和成本。陶瓷电容可用于输入和输出。\n\n 通过外置反馈电阻，输出电压可以设定为1.2V至VIN；或将输出1预置为1.8V或3.3V, 输出2预置1.5V或2.5V。如果某路输出高于1.2V，则另一路输出可设定至1V以下的电压。考虑负载、线路和温度等变化 • 电流模式、1.4MHz固定频率PWM工作\n• 180°错相工作减小输入电容\n• 在整个负载、线路和温度变化范围内，达到了±1%输出精确度\n• 保证750mA输出电流\n• 2.6V至5.5V的输入电压\n• 上电复位延迟16.6ms (MAX1970)或175ms (MAX1972和MAX1972)\n• 电源失效输出(仅MAX1970和MAX1972)\n• 上电复位输入(仅MAX1971)\n• 工作在xDSL带外\n• 采用更小元件的超紧凑设计\n• 0.8V至VIN可调输出或1.8V/3.3V和1.5V/2.5V的预置输出\n• 全部采用陶瓷电容\n• 软启动减小浪涌;
