MP4462  
3.5A, 4MHz, 36V  
Step-Down Converter  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP4462 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.

•
120μA Quiescent Current  
Wide 3.8V to 36V Operating Input Range  
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  
Output Adjustable from 0.8V to 30V  
Available in 3x3mm QFN10 and SOIC8E  
Packages.  
The wide 3.8V to 36V input range accommodates  
a variety of step-down applications, including  
those in an automotive input environment. A  
120µA 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.

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.  
In some applications, such as AM radio and  
ADSL applications, in which the device is  
sensitive to frequency band, the MP4462 can  
avoid the related EMI problem by setting the  
frequency at 4MHz.  
All MPS parts are lead-free and adhere to the RoHS directive. For MPS green  
status, please visit MPS website under Products, Quality Assurance page.
