MP1586  
3A, 28V, 50kHz to 400kHz  
Step-Down Converter  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP1586 is a high frequency step-down  
switching regulator with an integrated internal  
high-side high voltage power MOSFET. It  
provides 3A output with current mode control for  
fast loop response and easy compensation.  
•
•
Wide 4.5V to 28V Operating Input Range  
Programmable Switching Frequency from  
50kHz to 400kHz  
High-Efficiency Pulse Skipping Mode for  
Light Load  
•
•
•
•
Ceramic Capacitor Stable  
Internal Soft-Start  
Internally Set Current Limit without a  
Current Sensing Resistor  
Available in SOIC8E Package.  
The wide 4.5V to 28V input range accommodates  
a variety of step-down applications, including  
those in an automotive input environment. A  
115µA operational quiescent current allows use in  
battery-powered applications.  
•
High power conversion efficiency over a wide  
load range is achieved by scaling down the  
switching frequency at light load condition to  
reduce the switching and gate driving losses.

High Voltage Power Conversion  
Automotive Systems  
Industrial Power Systems  
Distributed Power Systems  
Battery Powered Systems  
The frequency foldback helps prevent inductor  
current runaway during startup and thermal  
shutdown provides reliable, fault tolerant  
operation.  
“MPS” and “The Future of Analog IC Technology” are Registered Trademarks of  
Monolithic Power Systems, Inc.  
The MP1586 is available in a thermally enhanced  
SOIC8E package.
