MP4461  
3.5A, 4MHz, 36V  
Step-Down Converter  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP4461 is a high frequency step-down  
switching regulator with an integrated internal  
high-side high voltage power MOSFET. It  
provides 3.5A output with current mode control for  
fast loop response and easy compensation.  
•
•
•
•
•
100μA Quiescent Current  
Wide 4.5V to 36V Operating Input Range  
3A Peak Switch Current  
150mΩ Internal Power MOSFET  
Up to 4MHz Programmable Switching  
Frequency  
Ceramic Capacitor Stable  
Internal Soft-Start  
Internally Set Current Limit without a  
Current Sensing Resistor  
The wide 4.5V to 36V input range accommodates  
a variety of step-down applications, including  
those in an automotive input environment. A  
100µA operational quiescent current allows use in  
battery-powered applications.  
•
•
•
•
•
Output Adjustable from 0.8V to 30V  
Available in 3x3 QFN10 Package.  
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.  
APPLICATIONS  
•
•
•
•
•
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.  
By switching at 4MHz, the MP4461 is able to  
prevent EMI (Electromagnetic Interference) noise  
problems, such as those found in AM radio and  
ADSL applications.  
“MPS” and “The Future of Analog IC Technology” are Registered Trademarks of  
Monolithic Power Systems, Inc.  
The MP4461 is available in small 3mm x 3mm  
QFN10 package.
