NCP3134: 2.9V to 5.5V, 4A, 2.2MHz, Integrated Synchronous DC-DC Step Down Converter

Description: The NCP3134 is a fully integrated synchronous buck...
  • The NCP3134 is a fully integrated synchronous buck converter capable of operating from 2.9V to 5.5V while delivering up to 4A. The NCP3134 operates at 2.2MHz, allowing for a smaller output filter and offering fast load transient response. The device can operate in DCM/CCM (higher efficiency at light loads) or Forced CCM mode to ensure fixed frequency operation. The device is offered in a small 3mm by 3mm QFN package.
  • Features
  • Automatic DCM/CCM and FCCM operating modes - Improve efficiency at light loads or use fixed frequency operating mode
  • 2.2MHz 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
  • 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 4A continuous current
  • Applications
  • 5V and 3.3V POL applications
  • End Products
  • servers/desktops/notebooks
  • solid state drives
  • base station/networking
  • Automotive infotainment
