Abstract :
In this paper, a power loss model of VRMs will first be given. Actual power loss distribution on VRMs will be estimated for various VRM conditions. Comments will be made from the observations of the results and suggestions be made from the point of view of gate driver chip design. Discussion of future improvement possibilities is presented.
