Abstract:
To accommodate the rapid development of the computer and information technology,the new generation of Central Processing Unit’s ( CPU) power supply voltage trends to be lower,while its current and current slew rate become larger. Therefore,as the dedicated power supply of CPU,voltage regulator module ( VRM) presents the following developmental trends: low voltage,large current output and good dynamic characteristics. This paper expounds the development of the topologies of VRM,which consist of the non-isolated,isolated and two-stage topologies. Several critical issues for the future design considerations of VRM are also pointed out in the end.
