MP2233  
High-Efficiency, 3A, 16V, 1.4MHz  
Synchronous, Step-Down Converter  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP2233 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 3A continuous  
output current with excellent load and line  
regulation over a wide input supply range. The  
MP2233 has synchronous mode operation for  
higher efficiency over the output current load  
range.  
Wide 4.5V-to-16V Operating Input Range  
80m/30mLow RDS(ON) Internal Power  
MOSFETs  
Proprietary Switching-Loss–Reduction  
Technique  
High-Efficiency Synchronous Mode  
Operation  
Fixed 1.4MHz Switching Frequency  
Can Synchronize to a 300kHz-to-3MHz  
External Clock  
Current-mode operation provides  
a
fast  
Externally-Programmable Soft-Start  
OCP and Hiccup  
Thermal Shutdown  
Output Adjustable from 0.8V  
Available in an 8-pin TSOT-23 Package  
transient response and eases loop stabilization.  
Protective features include over-current  
protection, thermal shutdown, and external SS  
control.  
The MP2233 requires a minimal number of  
readily-available external components and is  
available in a space-saving 8-pin TSOT23  
package.
