MP1484  
3A, 18V, 340KHz Synchronous Rectified  
Step-Down Converter  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
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.

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  
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  
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.
