Abstract: Voltage regulator module is power supply of processor. The choice of main topology is very important. The limitations of conventional nonisolated Buck and isolated topologies were analyzed. Based on the study of VRMs development, several novel directions were introduced, such as nonisolated topologies based on transformer, topologies derived from Buck converter, twostage VRM, currenttripler converter. In addition, the ideas, advantages and limitations, and applications were discussed.
Key words: voltage regulator module (VRM); topologies; currenttripler converter; Boost converter; complementary controlled bridge (CCB)
