STLUX385A数据手册集成电路（IC）的电源管理-专用规格书PDF

描述 Description

The STLUXTM family of controllers is a part of the STMicroelectronics digital devices tailored for lighting and power conversion applications. The STLUX controllers have been successfully integrated in a wide range of architectures and applications, starting from simple buck converters for driving multiple LED strings, boost for power factor corrections, half-bridge resonant converters for high power dimmable LED strings and up to full bridge controllers for HID lamp ballasts.
