MP1583  
3A, 23V, 385KHz  
Step-Down Converter  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP1583 is a step-down regulator with a  
built-in 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  
100mΩ Internal 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 23V Operating Input Range  
Output Adjustable from 1.22V to 21V  
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.  
APPLICATIONS  
The MP1583 requires a minimum number of  
external components, providing a compact  
solution.
