NCP3135 is a fully integrated synchronous buck converter capable of delivering up to 5A. The device operates from 2.9V to 5.5V, making them ideal for 3.3V and 5V bus applications. The NCP3135 offers high efficiency, fast load transient response, and can operate in CCM/DCM (automatic continuous/discontinuous modes) or FCCM (forced continuous conduction mode). High switching frequency reduces the output filter size. The device offers enable and power good indicator that can be used for sequencing. The NCP3135 is offered in a small 3mm x 3mm QFN package.
Features   Benefits
     
  • Automatic DCM/CCM and FCCM operating modes
  
  • Improve efficiency at light loads or use fixed frequency operating mode
  • 1.1MHz Switching Frequency
  
  • High switching frequency to minimize passives (inductor, capacitors)
  • 3mm by 3mm QFN package
  
  • Small size reduce board space. QFN thermally enhance for power dissipation
  • Output range from 0.6V to 0.84Vin
  
  • Flexibility allows same device for multiple applications
  • Over/Undervoltage, Overcurrent, and Overtemperature protection
  
  • Protect IC against faults
  • Internal 1ms soft start
  
  • Reduce inrush current during start up
  • Safe start up into prebias output
  
  • Prevents reverse current flow from output capacitor
  • Up to 5A continuous current
    
Applications   End Products
  • 5V and 3.3V POL applications
  
  • servers/desktops/notebooks
  • solid state drives
  • base station/networking
