MPQ4456  
Industrial Grade ,1A, 4MHz, 36V  
Step-Down Converter  
The Future of Analog IC Technology  
FEATURES  
DESCRIPTION  
Guaranteed Industrial Temp Range  
120μA Quiescent Current  
Wide 3.8V to 36V Operating Input Range  
300mΩ Internal Power MOSFET  
Up to 4MHz Programmable Switching  
Frequency  
The MPQ4456 is a high frequency step-down  
switching regulator with an integrated internal  
high-side high voltage power MOSFET. It  
provides 1 A output with current mode control  
for fast loop response and easy compensation.  
The wide 3.8V to 36V input range  
Ceramic Capacitor Stable  
Internal Soft-Start  
Extended PWM Operation Reduces Noise  
Up to 95% Efficiency  
Output Adjustable from 0.8V to 36V  
Available in 10-Pin 3x3 TQFN Package  
accommodates  
a
variety of step-down  
applications, including those in automotive  
systems. A 120µA operational quiescent current  
is suitable for use in battery-powered  
applications.  
Special controlled circuitry allows the MPQ4456  
to maintain PWM operation at low output  
currents. This lowers noise by reducing the  
pulse skipping.  
APPLICATIONS  
High Voltage Power Conversion  
Automotive Systems  
Industrial Power Systems  
Distributed Power Systems  
Battery Powered Systems  
By switching at 4MHz, the MPQ4456 prevents  
EMI (Electromagnetic Interference) noise  
problems, such as those found in AM radio and  
ADSL applications.  
All MPS parts are lead-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 MPQ4456 is available in thin 10-pin 3mm x 3mm  
TQFN package.
