DESCRIPTION  
FEATURES  
The MP28315 is a monolithic synchronous buck  
regulator. The device integrates 100m  
MOSFETS that provide 3A continuous load  
current over a wide operating input voltage of  
5V to 16V. Current mode control provides fast  
transient response and cycle-by-cycle current  
limit.  
3A Output Current  
Wide 5V to 16V Operating Input Range  
Integrated 100mPower MOSFET Switches  
Output Adjustable from 0.925V to 13V  
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. In shutdown mode, the supply  
current drops below 1µA.  
This device, available in an 8-pin SOIC  
package, provides a very compact system  
solution with minimal reliance on external  
components.
