单/双通道稳压器为DDR存储器和DC-DC转换提供高效率电源

飞思卡尔MC34712/3/6/7器件为图形卡、刀片式服务器、机顶盒和计算应用提供了专业化电源处理能力,并将效率提高到93%。这些高度集成的功率调节器是那些空间受限的小型高效设备的理想之选。

飞思卡尔开发了一系列DC-DC开关调节电源管理IC(PMIC)器件。这些产品整合了高性能开关稳压器,为微处理器的内核提供直接供电。并且,它们还具有低压降(LDO)线性稳压控制电路,用于为微处理器提供I/O和总线电压。各种稳压模式和电压设置可以经由微控制器通过配置器件上的模式和控制终端来控制。

开关稳压器是一种高效率的同步降压稳压器,集成了N通道功率MOSFET,可以提供保护功能,并实现节省空间的小型设计。这些PMIC器件整合了众多高级特性,如精确控制的上电/掉电时序,从而保证了CPU和电源系统的正常工作与保护。这些功能通过飞思卡尔半导体公司的SMARTMOS™技术来实现。
