MP2377  
3A, 21V, 600kHz  
Step-Down Converter  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP2377 is a monolithic step-down switch  
mode converter with a built in high-side power  
MOSFET. It achieves 3A continuous output  
current over a wide input supply range with  
excellent load and line regulation.  
Wide 4.5V to 21V Operating Input Range  
3A Output Current  
100mInternal Power MOSFET Switch  
Power Good Indicator  
Fixed 600kHz Frequency  
Synchronizable to >1MHz External Clock  
Over Current Latch Off Protection  
Thermal Shutdown  
Output Adjustable from 0.81V  
Stable with Low ESR Output Ceramic  
Capacitors  
Available in Thermally Enhanced 8-Pin  
SOIC Packages  
Supports Soft-Start into Pre-Biased Output  
Current mode operation provides fast transient  
response and eases loop stabilization.  
Fault condition protection includes current limiting  
and thermal shutdown.  
The MP2377 requires a minimum number of  
readily available standard external components  
and is available in 8-pin SOIC packages with  
exposed pad.
