NCP3136 is a fully integrated synchronous buck converter for 3.3 V and 5 V step−down applications. It can provide up to 6.5 A instantaneous current. NCP3136 supports high efficiency, fast transient response and provides power good indicator. The control scheme includes two operation modes: FCCM and automatic CCM/DCM. In automatic CCM/DCM mode, the controller can smoothly switch between CCM and DCM, where converter runs at reduced switching frequency with much higher efficiency. NCP3136 is available in 3 mm x 3 mm QFN16 pin 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 1.5ms soft start
 
  • Reduce inrush current during start up
  • Safe start up into prebias output
 
  • Prevents reverse current flow from output capacitor
  • hiccup mode during short circuit conditions
 
  • prevents mosfet damage and recovery when short removed
  • Up to 5A continuous current
   
Applications   End Products
  • 5V and 3.3V POL applications
 
  • servers/desktops/notebooks
  • solid state drives
  • base station/networking
