主要产品

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。 Read more

Our products and solutions

Our VIPerPlus high-voltage converters help design high-efficiency, cost-effective off-line buck and buck-boost converters with a minimum component count and enhanced reliability thanks to a set of features including pulse skip protection that can help reduce peak current at start-up allowing the use of smaller, less expensive inductors.

In addition, we provide an extensive set evaluation and development boards as well as reference designs.
