AME5269

AME AME5269 2A, 28V, 340KHz Synchronous Rectified Step-Down Converter n General Description n Features The AME5269 is a fixed frequency monolithic synchronous buck regulator that accepts input voltage from 4.75V to 28V. Two NMOS switches with low on-resistance are integrated on the die. Current mode topology is used for fast transient response and good loop stability. Shutdown mode reduces the input supply current to less than 1µA. An adjustable soft-start prevents inrush current at turn-on. This device is available in SOP-8 package. n Applications l Distributed Power System l Networking System l FPGA, DSP, ASIC Power Supplies l Notebook Computers l 2A Output Current l Wide 4.75V to 28V Operating Input Range l Integrated Power MOSFET Switches l Output Adjustable from 0.925V to 25V l Up to 95% Efficiency l Programmable Soft Start l Stable with Low ESR Ceramic Output Capacitors l Cycle-by Cycle Over Current Protection l Fixed 340KHz Frequency l Input Under Voltage Lockout l System ...
