MP2259  
1A, 16V, 1.4MHz  
Step-Down Converter  
The Future of Analog IC Technology  
FEATURES  
DESCRIPTION  
1A Output Current  
The MP2259 is a monolithic integrated step-  
down switch mode converter with an internal  
power MOSFET. It achieves 1A continuous  
output current over a wide input supply range  
with excellent load and line regulation.  
0.5Internal Power MOSFET Switch  
Stable with Low ESR Output Ceramic  
Capacitors  
Up to 92% Efficiency  
0.1μA Shutdown Mode  
Fixed 1.4MHz Frequency  
Thermal Shutdown  
Cycle-by-Cycle Over Current Protection  
Wide 4.5V to 16V Operating Input Range  
Output Adjustable from 0.81V to 14V  
Available in TSOT23-6 and SOT23-6 Packages  
Current mode operation provides fast transient  
response and eases loop stabilization.  
Fault condition protection includes cycle-by-cycle  
current limiting and thermal shutdown.  
The MP2259 requires a minimum number of  
readily available standard external components.  
The MP2259 is available in TSOT23-6 and  
SOT23-6 packages.
