MP2565  
2.5A, 4MHz, 50V  
Step-Down Converter  
The Future of Analog IC Technology  
FEATURES  
DESCRIPTION  
120μA Quiescent Current  
The MP2565 is a high frequency step-down  
switching regulator with an integrated internal  
high-side high voltage power MOSFET. It  
provides 2.5A output with current mode control for  
fast loop response and easy compensation.  
Wide 4.5V to 50V Operating Input Range  
220mInternal Power MOSFET  
Up to 4MHz Programmable Switching  
Frequency  
High-Efficiency, Light-Load operation  
Stable with Ceramic Capacitor  
Internal Soft-Start  
Internally Set Current Limit without external  
Current Sensing Resistor  
The wide 4.5V to 50V input range accommodates  
a variety of step-down applications, including  
those in an automotive input environment. A 12µA  
shutdown mode supply current allows use in  
battery-powered applications.  
Up to 95% Efficiency  
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.  
Output Adjustable from 0.8V to 47V  
Available in 3x3 QFN10 and Thermally  
Enhanced SOIC8 Packages  
APPLICATIONS  
The frequency foldback helps prevent inductor  
current runaway during startup and thermal  
shutdown provides reliable, fault tolerant  
operation.  
High Voltage Power Conversion  
Automotive Systems  
Industrial Power Systems  
Distributed Power Systems  
Battery Powered Systems  
By switching at 4MHz, the MP2565 is able to  
prevent EMI (Electromagnetic Interference) noise  
problems, such as those found in AM radio and  
ADSL applications.  
All MPS parts are lead-free, halogen free, and adhere to the RoHS directive.  
For MPS green status, please visit MPS website under Quality  
Assurance. “MPS” and “The Future of Analog IC Technology” are Registered  
Trademarks of Monolithic Power Systems, Inc.  
The MP2565 is available in small 3mm x 3mm  
QFN10 and thermally enhanced SOIC8 packages.
