The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP2351 is a monolithic step down switch  
mode converter with a built in internal power  
MOSFET. It achieves 1.5A continuous output  
current over a wide input supply range with  
excellent load and line regulation.  
1.5A Output Current  
0.18Internal Power MOSFET Switch  
Stable with Low ESR Output Ceramic  
Capacitors  
Up to 93% Efficiency  
20µA Shutdown Mode  
Current mode operation provides fast transient  
response and eases loop stabilization.  
Fixed 1.4MHz Frequency  
Thermal Shutdown  
Fault condition protection includes cycle-by-cycle  
current limiting, short circuit frequency foldback  
and thermal shutdown. In shutdown mode the  
regulator draws 20µA of supply current.  
Cycle-by-Cycle Over Current Protection  
Wide 4.75V to 23V Operating Input Range  
Output Adjustable from 1.23V to 16V  
Programmable Under Voltage Lockout  
Frequency Synchronization Input  
Available in QFN (3mm x 3mm) and tiny  
10-Pin MSOP Packages  
The MP2351 requires a minimum number of  
readily available standard external components.
