MP2305  
2A, 23V Synchronous Rectified  
Step-Down Converter  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP2305 is a monolithic synchronous buck  
regulator. The device integrates 130m  
MOSFETS that provide 2A continuous load  
current over a wide operating input voltage of  
4.75V to 23V. Current mode control provides  
fast transient response and cycle-by-cycle  
current limit.  
2A Output Current  
Wide 4.75V to 23V Operating Input Range  
Integrated 130mPower MOSFET Switches  
Output Adjustable from 0.923V to 20V  
Up to 93% Efficiency  
Programmable Soft-Start  
Stable with Low ESR Ceramic Output Capacitors  
Fixed 340kHz Frequency  
An adjustable soft-start prevents inrush current  
at turn-on. Shutdown mode drops the supply  
current to 1μA.  
Cycle-by-Cycle Over Current Protection  
Input Under Voltage Lockout  
This device, available in an 8-pin SOIC  
package, provides a very compact system  
solution with minimal reliance on external  
components.  
APPLICATIONS  
Distributed Power Systems  
Networking Systems  
FPGA, DSP, ASIC Power Supplies  
Green Electronics/ Appliances  
Notebook Computers
