UBA2071ATS中文资料Half bridge control IC for CCFL backlighting数据手册恩XP规格书

描述 Description

The UBA2071ATS is ahigh voltage IC intended to drive Cold Cathode Fluorescent Lamps (CCFLs) or External Electrode Fluorescent Lamps (EEFLs) for backlighting applications. It can drive a half bridge circuit made up of two NMOSFETs with a supply voltage of up to 550 V, so the inverter can be supplied directly from a 400 V PFC bus.
