MP9442  
High Efficiency 2A, 36V, 600kHz  
Synchronous Step-Down Converter  
with Power Good  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP9442 is a high-frequency, synchronous,  
rectified, step-down, switch-mode converter  
with built-in power MOSFETs. It offers a very  
compact solution to achieve a 2A continuous  
output current with excellent load and line  
regulation over a wide input supply range. The  
MP9442 has synchronous mode operation for  
higher efficiency over the output current load  
range.
