AX3484 3A, 23V, 340kHz Synchronous Rectified Step-Down Converter
性能描述：
The AX3484 is a monolithic synchronous buck regulator. The device integrates two 100mΩ MOSFETs, and provides 3A of continuous load current over a wide input voltage of 4.75V to 23V. Current mode control provides fast transient response and Cycle-by-Cycle current limit.
An adjustable soft-start prevents inrush current at turn-on, and in shutdown mode the supply current drops to 1μA.
This device, available in an 8-pin SOP with exposed pad package, provides a very compact solution with minimal external components.
特点：
• 3A Output Current
• Wide 4.75V to 23V Operating Input Range
• Integrated 100mΩ Power MOSFET Switches
• Output adjust from VFB to 20V
• Up to 95% Efficiency
• Programmable Soft-Start
• Stable with Low *R Ceramic Output Capacitors
• Fixed 350KHz Frequency
• Cycle-by-Cycle Over Current Protection
• Thermal shutdown and short circuit protections
