MSN12AD60-RUD  EVB  GUIDE 

 

GENERAL DESCRIPTION:

 

 

The EVB guide is a reference design allowing the user to evaluate the performance of the 
MSN12AD60-RUD. The MSN12AD60-RUD is a digital synchronous DC/DC power module. The 
digital controller, power MOSFETs and most of support components are integrated in one 
hybrid package. 
The module is a dual phase digital synchronous buck with adaptive loop compensation, for 
point-of-load (POL) applications. The output can supply 0.6V to 1.8V, and can be configured 
and  controlled  via  PMBus,  with  a  single  resistor,  or  through  programming  stored  in  the 
non-volatile memory (NVM). The control algorithm adapts to the application environment, on 
a  cycle-by-cycle  basis,  optimizing  performance,  regardless  of  variation  such  as  initial 
component tolerance, temperature, input voltage, output voltage and load characteristics 
(capacitive / inductive etc.). The module also integrates adaptive phase add and drop which 
can improves system loss by up to 30%.
