MP28311  
3A, 28V, 340KHz Synchronous Rectified  
Step-Down Converter  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP28311 is a monolithic synchronous buck  
regulator. The device integrates power  
MOSFETS that provide 3A continuous load  
current over a wide operating input voltage of  
4.75V to 28V. Current mode control provides  
fast transient response and cycle-by-cycle  
current limit.  
3A Output Current  
Wide 4.75V to 28V Operating Input Range  
Integrated Power MOSFET Switches  
Output Adjustable from 0.8V to 25V  
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 and  
3x3 QFN10 Packages  
An adjustable soft-start prevents inrush current  
at turn-on. In shutdown mode, the supply  
current drops to 1μA.  
This device, available in 8-pin SOIC and 3x3  
10-pin QFN packages, provides a very compact  
system solution with minimal reliance on  
external components.
