2A, 18V Synchronous Rectified  
Step-Down Converter  
The Future of Analog IC Technology  
FEATURES  
DESCRIPTION  
2A Output Current  
The MP1482 is a monolithic synchronous buck  
regulator. The device integrates two 130m  
MOSFETs, and provides 2A of continuous load  
current over a wide input voltage of 4.75V to  
18V. Current mode control provides fast  
transient response and cycle-by-cycle current  
limit.  
Wide 4.75V to 18V Operating Input Range  
Integrated 130mPower MOSFET Switches  
Output Adjustable from 0.923V to 15V  
Up to 93% Efficiency  
Programmable Soft-Start  
Stable with Low ESR Ceramic Output Capacitors  
Fixed 340kHz Frequency  
Cycle-by-Cycle Over Current Protection  
Input Under Voltage Lockout  
8–Pin SOIC  
An adjustable soft-start prevents inrush current  
at turn-on, and in shutdown mode the supply  
current drops to 1µA.  
This device, available in an 8-pin SOIC  
package, provides a very compact solution with  
minimal external components.  
APPLICATIONS
