开始

当DC-DC开关转换器的输出电压低于输入电压(有/无输入-输出隔离)时,采用降压拓扑。

我们有大量的降压调节器(配集成功率开关)和多相单相多输出控制器,提供广泛的特性(包括软启动),以尽量减少浪涌电流,并通过Power-Good(供电正常信号)确保正常的加电顺序。可编程器件也可以帮助设计可根据特定的EMI、EMC、效率和功率密度目标、以及用例进行微调的降压转换器。

我们还开发了一种隔离式单级48V直接到负载点(PoL)谐振转换解决方案,可用于符合Intel VR13和VR12.5规范的CPU或DDR内存。意法半导体还提供一种完全可扩展的解决方案,能够管理高达6个具有动态电池脱落和脉冲跳跃特性的交错并联电池。

此外,我们还提供全套评估与开发工具(包括参考设计),帮助缩短产品上市时间。
