MP1593  
3A, 28V, 385kHz  
Step-Down Converter  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP1593 is a step-down regulator with an  
internal Power MOSFET. It achieves 3A of  
continuous output current over a wide input  
supply range with excellent load and line  
regulation.  
3A Output Current  
Programmable Soft-Start  
100mInternal Power MOSFET Switch  
Stable with Low ESR Output Ceramic  
Capacitors  
Up to 95% Efficiency  
20μA Shutdown Mode  
Fixed 385kHz Frequency  
Thermal Shutdown  
Cycle-by-Cycle Over Current Protection  
Wide 4.75V to 28V Operating Input Range  
Output Adjustable from 1.22V  
Under-Voltage Lockout  
Current mode operation provides fast transient  
response and eases loop stabilization.  
Fault condition protection includes cycle-by-cycle  
current limiting and thermal shutdown. An  
adjustable soft-start reduces the stress on the  
input source at startup. In shutdown mode the  
regulator draws 20µA of supply current.  
The MP1593 requires a minimum number of

available  
external  
components,  
providing a compact solution.  
APPLICATIONS
