开始

基于buck（或降压式）、以及buck-boost（或升/降压式）拓扑的离线式转换器将电源转换为稳压直流输出（可以是正输出，也可以是负输出），无需隔离变压器，只需调节功率开关的占空比。

电感器件中的电流波形定义转换器的运行模式（当电感器件中的电流从未降到零时是连续模式，当电流在给定的时间间隔内保持为零时是不连续模式）、电感器件电流在某个点为零时的边界模式或过渡模式。这两种拓扑都可以使用低成本的电感器件进行能量存储和从输入到输出的转换。

我们的VIPerPlus高压转换器具有一系列功能，包括脉冲跳变保护（可以帮助减少启动时的峰值电流，允许使用更小、更便宜的电感器件），可帮助设计高效率且经济划算的离线降压式和升/降压式转换器（元件数最少，可靠性更高）。

此外，我们还提供广泛的评估和开发板、以及参考设计。
