MP4561  
1.5A, 2MHz, 55V  
Step-Down Converter  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP4561 is a high frequency step-down  
switching regulator with integrated internal high-  
side high voltage power MOSFET. It provides  
1.5A output with current mode control for fast loop  
response and easy compensation.  
Wide 3.8V to 55V Operating Input Range  
300mInternal Power MOSFET  
Up to 2MHz Programmable Switching  
Frequency  
140μA Quiescent Current  
Ceramic Capacitor Stable  
External Soft-Start  
Up to 95% Efficiency  
Output Adjustable from 0.8V to 52V  
Available in 3x3mm 10-Pin QFN  
The wide 3.8V to 55V input range accommodates  
a variety of step-down applications, including  
those in automotive input environment. A 12µA  
shutdown mode supply 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.  
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.  
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.

Monolithic Power Systems, Inc.  
By switching at 2MHz, the MP4561 is able to  
prevent EMI (Electromagnetic Interference) noise  
problems, such as those found in AM radio and  
ADSL applications.  
The MP4561 is available in small 3mm x 3mm  
10-pin QFN with exposed pad package.
