STMicroelectronics STLUX385A

Description

The STLUX385A device is part of the STLUX™ family of STMicroelectronics® digital devices tailored for lighting and power conversion applications. The STLUX385A has 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 bridgecontrollers for HID lamp ballasts.
