MP2318  
High Efficiency 2A, 24V, 2MHz  
Synchronous Step-Down Converter  
DESCRIPTION  
FEATURES  
The MP2318 is a high frequency synchronous  
rectified step-down switch mode converter with  
built-in internal power MOSFETs. It offers a  
very compact solution to achieve 2A continuous  
output current over a wide input supply range  
with excellent load and line regulation.  
Wide 4.5V to 24V Operating Input Range  
2A Load Current  
90mΩ/40mΩ Low Rds(on) Internal Power  
MOSFETs  
Low Quiescent Current  
High Efficiency Synchronous Mode  
Operation  
Fixed 2MHz Switching Frequency  
AAM Power Save Mode  
Internal Soft Start  
OCP Protection and Hiccup  
Thermal Shutdown  
Current mode operation provides fast transient  
response and eases loop stabilization.  
Full protection features include OCP and  
thermal shut down.  
The MP2318 requires a minimum number of  
readily available standard external components  
and is available in a space saving 8-pin  
TSOT23 package.  
Output Adjustable from 0.8V  
Available in an 8-pin TSOT-23 package  
APPLICATIONS  
Notebook Systems and I/O Power  
Digital Set Top Boxes  
Flat Panel Television and Monitors
