/MPS MP1484EN-LF-Z 3A, 18V, 340KHz Synchronous Rectified Step-Down Converter

MPS MP1484EN-LF-Z 3A, 18V, 340KHz Synchronous Rectified Step-Down Converter

The MP1484 is a monolithic synchronous buck regulator.

  • Brand:

    MPS
  • Product Details

DESCRIPTION 

The MP1484 is a monolithic synchronous buck regulator. The device integrates top and bottom 85mȍ MOSFETS that provide 3A of continuous load current over a wide operating input voltage of 4.75V to 18V. 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 below 1μA. 

The MP1484 is PIN compatible to the MP1482 2A/18V/Synchronous Step-Down Converter.


FEATURES 

  • 3A Continuous Output Current 

  • Wide 4.75V to 18V Operating Input Range 

  • Integrated 85mȍ Power MOSFET Switches 

  • Output Adjustable from 0.925V to 20V 

  • Up to 95% Efficiency x Programmable Soft-Start 

  • Stable with Low ESR Ceramic Output Capacitors 

  • Fixed 340KHz Frequency 

  • Cycle-by-Cycle Over Current Protection 

  • Input Under Voltage Lockout 

  • Thermally Enhanced 8-Pin SOIC Package 


APPLICATIONS 

  • FPGA, ASIC, DSP Power Supplies 

  • LCD TV 

  • Green Electronics/Appliances x Notebook Computers
