0.7V ~ Vcc-1V输入,4A 1ch超低饱和线性电源 BD3522EFV

BD3522EFV是以超低电压输入实现超低电压输出的芯片组用线性稳压器。内置的功率晶体管使用N-MOSFET,可实现在低于导通电阻 (RON=50mΩ(Max))产生的电压差的超低输入输出电压差下使用。通过减小输入输出电压差,实现大电流(IOUTMAX=4.0A) 输出,还可降低转换损耗,因而能实现开关电源的置换。BD3522EFV不需要开关电源所需的扼流线圈、整流用二极管、功率晶体管,可降低整机总成本,实现小型化。BD3522EFV可使用外接电阻在0.65V~2.7V范围内任意设置输出电压。使用NRCS端子可调整电压输出的启动时间,因而能对应整机的电源时序。
