EC3284中文资料3A,23V,Syn. Rectified Step-Down Converter数据手册E-CMOS规格书

描述 Description

The EC3284 is a monolithic synchronous buck regulator.The device integrates two 90mΩ MOSFETs, and provides 3A of continuous load current over a wide input voltage of 4.75V to 23V. Current mode control provides fast transient response and cycle-by-cycle current limit. An adjustable soft-start prevents inrush current at turn-on, and in shutdown mode the supply current drops to 1µA. This device available in an SOP8(Exposed PAD)package, provides a very compact solution with minimal external components.
