800mA、2MHz、PWM DC-DC降压型转换器，带有复位

MAX1572是一款固定频率、同步降压型DC-DC转换器，能够为PCB面积受限制、需要高转换效率的便携设备中的低电压微处理/DSP核提供电源。经过优化的特性可在较宽的负载范围内保持高效，具有小尺寸外部元件、低输出纹波和优异的瞬态响应特性。输入电压范围2.6V至5.5V，输出电压可由内部固定在0.75V至2.5V，每级增量为50mV，保证输出电流达800mA。2MHz的高开关频率允许选用小巧的低成本电容和小尺寸电感，节省功耗的脉冲群模式能够在轻载下使静态电流减小至48µA (典型值)。为了降低噪声和RF干扰，转换器可以配置为强制PWM工作模式。\nMAX1572内部具有一个低导通电阻的MOSFE • 效率高达97% \n• 2MHz PWM开关频率 \n• 保证800mA输出电流 \n• 48µA低静态电流 \n• 省电模式：脉冲群、脉冲跳频、强制PWM模式 \n• 预置0.75V至2.5V输出范围(50mV输出增量) \n• 电压定位负载瞬变 \n• 5mVP-P输出纹波 \n• 微型2.2µH电感 \n• 10µF陶瓷输出电容 \n• 0.1µA低关断电流 \n• 无需外部肖特基二极管 \n• 零浪涌电流软启动 \n• 170ms (最小) /RESET输出 \n• 小型12引脚、4mm x 4mm薄型QFN封装;
