PWM、PWM/PFM切换、升降压DC/DC控制器

XC9302系列是内置高速低通态电阻驱动器的通用高频升降压DC/DC转换控制器。通过外置2个晶体管,线圈,二极管和电容器共4种元件，可构建大电流,高性能的升降压DC/DC转换器。\n\n 在器件内，可在2.4V～6.0V(±2.5％)范围，以0.1V的间隔设定输出电压。\n\n 由于开关频率高达180kHz，300kHz可使用小型外置元件。\n\n 在小负载时，PWM/PFM切换控制型XC9302系列的工作从PWM工作模式切换为PFM工作模式。因此，能够在小负载至大输出电流整个负载范围内，达到高效工作。在内部设定了10ms的软启动时间，以此防止通电时的输入冲击电流和输出 ·输入电压范围：2.0V~10V\n·输出电压范围：2.4V~6.0V(±2.5%),(0.1V间隔)\n·工作频率：180KHz,300kHz(±15%)\n·输出电流：250mA(VIN=2.4V,VOUT=3.3V)\n·高转换效率：81%(TYP.)@5.0V, 78%(TYP.)@3.3V\n·待机电流：ISTB=0.5μA(MAX.)\n·最大占空比：85%(TYP.)\n·功能：输出电压和外围器件自由设定;
