BD9328EFJ数据手册集成电路（IC）的DCDC开关稳压器规格书PDF

描述 Description

BD9328EFJ是同步整流降压DC/DC转换器，内置有低导通电阻的功率MOSFET。拥有宽输入电压范围，并可进行大约2A电流的连续输出。使用少量外置元器件即可构成，控制了成本。由于是电流模式控制DC/DC转换器，所以具有高速响应性，相位补偿也简单。ROHM recommends BD9C301FJ for new design.Please refer to Buck DC/DC Converter IC Replacement Guide for more information.
