2019-7-17MC34280-电源和管理IC，用于手持式电子产品
MC34280电源集成电路提供两个升压稳压输出和一些电源管理监督功能。监管者采用脉冲频率调制（PFM）的。主升压调节器输出可外部调整从2.7V到5V。内部同步整流器是用来确保高效率（达到87％）。辅助调节器内置的可配置功率晶体管产生广泛的积极电压（可用于液晶显示屏的对比度电压使用）。该电压可调整，由+5 V至+25 V的外部电位器;或由微处理器，数字化，通过一个6位内部DAC。该MC34280是专为电池供电的手持式产品。随着低启动电压从1V和低静态电流（典型35毫安）的MC34280是最适合工作于12节AA / AAA电池。此外，监督的功能，如低电池检测，CPU电源上电复位，及后备电池控制，也
