MP2308  
18V, 4A Synchronous  
Step-Down Coverter  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP2308 is a synchronous rectified step-  
down switch mode converter with built in  
internal power MOSFETs. It offers a very  
compact solution to achieve 4A continuous  
output current over a wide input supply range  
with excellent load and line regulation. The  
MP2308 has synchronous mode operation for  
higher efficiency over output current load range.  
Wide 4.75V to 18V Operating Input Range  
4A Output Current  
Low Rds(ON) Internal Power MOSFETs  
300kHz-2MHz Programmable Switching  
Frequency  
EN ON/OFF Control  
Light Load Mode Selectable  
External Soft Start  
Current mode operation provides fast transient  
response and eases loop stabilization. Full  
protection features include OCP and thermal  
shut down.  
OCP and Thermal Shutdown  
Available in 14-pin QFN2x3 Package  
APPLICATIONS  
DSL Modems  
Cable Modems  
Set Top Boxes  
The MP2308 requires a minimum number of  
readily available standard external components  
and is available in a space saving 2mm x 3mm  
14-pin QFN package.  
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.
