With the rapid development of global AI, the demand for computing power has risen sharply, and the performance requirements for computing power have also increased accordingly, which has promoted the development of GPU power and efficiency. As an important power supply module of GPU, VRM's power density and efficiency have also been improving year by year. To be one of the key components of VRM, power inductor plays a very important role in the efficiency and power density of VRM. In this PPT, we mainly introduce the new generation of high-power-density MHz high-frequency power inductor, it adopts a completely new metal magnetic powder material and metal sintering technology. The developed copper-iron sintered inductors have extremely low high-frequency losses, higher initial inductance, excellent DC superposition characteristics, good heat dissipation performance, and smaller volume that enhance the power density and efficiency of GPU VRM.
