DESCRIPTION  
FEATURES  
The MP2359 is a monolithic step-down switch  
mode converter with a built-in power MOSFET.  
It achieves 1.2A peak 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.  
1.2A Peak Output Current  
0.35Internal 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 24V Operating Input Range  
Output Adjustable from 0.81V to 15V  
Available in TSOT23-6 and SOT23-6  
Packages  
The MP2359 requires a minimum number of  
readily available standard external components.  
The MP2359 is available in TSOT23-6 and  
SOT23-6 packages.
