解决方案
DC-DC开关转换器用于在局部为系统的任何组件或部件提供所需的直流电压和电流。根据应用的输入和输出电压之间的关系,工程师必须选择最佳的功率拓扑 — 降压升压降压-升压或逆变,以及是否进行同步整流。或者他们可以决定使用基于单片IC或离散功率开关和控制器的实现 — 甚至高级数字实现。无论他们的选择是什么,合适的半导体产品是满足他们特定设计目标(效率和尺寸)的关键。 Read more

升压转换器

在升压DC-DC转换器中,输出电压高于输入电压,包括在浮动升压拓扑中,输出不与输入共用参考点。升压DC-DC拓扑通常用于电池供电的设备,以产生高于电池电压的供电轨。这些设计要求高效率和超低待机电流,并且体积小,能够满足物联网便携式和可穿戴设备的要求。

降压-升压转换器

In a buck-boost DC-DC converter topology, the output voltage can be higher or lower than the input voltage. Often used in battery-operated equipment, buck-boost DC-DC converters require high-efficiency and ultra-low stand-by current  as well as a sma
