STNRG328A数据手册集成电路（IC）的电源管理-专用规格书PDF

描述 Description

STNRG devices are a part of the STNRG family of STMicroelectronics® digital devices designed for advanced power conversion applications.
The STNRG improves the design of the successful STLUX™ family, now integrated in a wide range of LED driver architectures, to support industrial power conversion applications such as PFC+LLC, interleaved LC DC/DC, interleaved PFC for smart power supplies as well as the full bridge for pilot line drivers for electric vehicles.
