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%.
