EC3293数据手册E-CMOS中文资料规格书

描述 Description

TheEC3293isahigh-frequency,synchronous, rectified, step-down,switch-modeconverter with internalpower MOSFETs.Itoffersaverycompact solution to achieve a3Acontinuousoutputcurrentover a wide input supply range,withexcellentloadandline regulation. The EC3293 hassynchronous-mode operation for higher efficiencyovertheoutput current-loadrange. Current-modeoperation providesfasttransient response and easesloop stabilization.
