AX3804 2A, 23V, 500KHz Synchronous Rectified Step-Down  Converter
性能描述：
      The AX3804 is a monolithic synchronous buck regulator. The device integrates two 110mΩMOSFETs, andprovides 2A of continuous load current over a wide input voltage of 4.75V to 23V.Current mode control providesfast transient response and  cycle-by-Cycle current limit.
      Internal soft-start prevents inrush current at turn-on, and in shutdown mode the supply current drops to5μA.
      This device, available in SOP-8L and SOP-8L-EP package, provides a very compact solutionwith minimalexternal components.

特点：
• 2A Output Current
• Wide 4.75V to 23V Operating Input Range
• Integrated 110mΩ Power MOSFET Switches
• Output adjust from VFB to 20V
• Internal compensation
• Up to 94% Efficiency
• Stable with Low *R Ceramic Output Capacitors
• Fixed 500KHz Frequency
• Cycle-by-Cycle Over Current Protection
• Thermal shutdown and short circuit protections
