MP4570  
3A, 4.5V-55V Input, Frequency Programmable,  
Fully Integrated Synchronous, Step-Down Converter  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP4570 is a frequency programmable step-  
down switching converter with integrated internal  
high-side and low side power MOSFETs. It can  
provide 3A continuous output current with peak  
current control for excellent transient response  
and efficiency performance.  
Wide Input Voltage Range: 4.5V to 55V  
90mΩ and 70mΩ Internal High and Low  
Power MOSFETs  
Peak Current Mode Control  
Programmable Switching Frequency  
Stable Independent on Output Capacitors  
Optional External Soft Start  
OCP Protection with Valley Current  
Detection  
Support External SYNC Clock  
OVP Protection  
Current Limit Decreasing during Output  
Short for Better Thermal Performance  
Power Good Indication  
The wide 4.5V to 55V input voltage range  
accommodates  
a
variety of step down  
applications, including those applications in  
industrial, PoE, automotive and printer with DC  
high voltage bus.  
The MP4570 uses peak current mode control to  
regulate the output voltage. The chip provides  
over current protection with valley current  
detection which is used to avoid current running  
way. Also it has accurate and reliable over  
voltage protection, and auto recovery thermal  
protection. In addition, the optional external soft  
start is available. Enable and power good  
indication function can be used to power track  
easily. In order to increase the efficiency,  
MP4570 will automatically scaling down the  
switching frequency when load is light.  
Meanwhile, the low side MOSFET will be turned  
off to reduce driver loss when zero inductor  
current is detected. MP4570 also features as a  
fully integrated solution with both high side and  
low side power MOSFETs. Synchronous  
operation mode with integrated low side  
MOSFET is much helpful to reduce the  
conduction loss and also beneficial to reduce  
external components space and save the cost.  
Thermal Shutdown Protection  
Available in a TSSOP-20 EP Package.  
APPLICATIONS  
PoE Input Non-isolated Buck  
Industrial Power Systems  
Printers and Scanners  
Automotive Power Systems  
Distributed Power Systems
