AA18359数据手册Agamem中文资料规格书

描述 Description

AA18359 is a 1.4MHz fixed frequency PWM non-synchronous setp-down regulator.AA18359 is operated from 4.5V to 16V,and the generatedoutput is adjustable from 0.81V to 14V,and the output current can be up to 1A with execllent load and line regulation.Current mode operation provides fast transient response and eases loop stabilization.The turn on resistance of the popwer MOSFET switches is 0.5Ω.Shutdown current is almost 0μA. AA18359 based solution is with minimum external components.AA18359 is available in the SOT26L package, and it is RoHS compliant and 100% lead (Pb) free.
