Overview 

Introduction 

The EVKT-MPM3695-25-A is an evaluation kit for  the single-phase configuration of the MPM3695-25. 
The  MPM3695-25  is  a  4mm  tall,  scalable,  and fully  integrated  power  module  with  a  PMBus  interface. 
The MPM3695-25 offers a complete power solution that achieves up to 25A of output peak current with 
excellent  load  and  line  regulation  over  a  wide  input  voltage  range. 

MPS’s  proprietary,  multi-phase 

constant-on-time (MCOT) control provides ultra-fast transient response and simple loop compensation. 
This kit allows for quick evaluation and module configurations through PMBus interface.
