MP2270  
1.8A, 24V, 700kHz  
Step-Down Converter  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP2270 is a monolithic step-down switch  
mode converter with a built-in internal power  
MOSFET. It achieves 1.8A continuous output  
current over a wide input supply range with  
excellent load and line regulation. Current mode  
operation provides fast transient response and  
eases loop stabilization. Fault condition  
protection includes cycle-by-cycle current limiting  
and thermal shutdown.  
1.8A Continuous Output Current  
0.3Internal Power MOSFET Switch  
Stable with Low ESR Output Ceramic  
Capacitors  
0.1μA Shutdown Mode  
Fixed 700kHz Frequency  
Thermal Shutdown  
Cycle-by-Cycle Over Current Protection  
Wide 4.5V to 24V Operating Input Range  
Output Adjustable from 0.81V to 20V  
Available in a 10-pin Exposed Pad MSOP  
Package  
The MP2270 requires a minimum number of  
readily available standard external components.  
The MP2270 is available in a 10-pin exposed pad  
MSOP package.
