Product Overview NCP3134: 2.9V to 5.5V, 4A, 2.2MHz, Integrated Synchronous DC-DC Step Down Converter
●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
■2.2MHz Switching Frequency
■3mm by 3mm QFN package
■Over/Undervoltage, Overcurrent, and Overtemperature protection
■Internal 1ms soft start
■Safe start up into prebias output
■Up to 4A continuous current
●Benefits
■Improve efficiency at light loads or use fixed frequency operating mode
■High switching frequency to minimize passives (inductor, capacitors)
■Small size reduce board space. QFN thermally enhance for power dissipation
■Protect IC against faults
■Reduce inrush current during start up
■Prevents reverse current flow from output capacitor
