N2 - The paper proposes an integrated GaN-based power converter, which has these features of a 3-D integrated magnetic component with alloy materials, improving the power density. Besides, the 3-D integrated magnetic component with alloy materials has high thermal conductivity, which can be regarded as a heat sink for an integrated GaN-based power module and further increase the power density. A comprehensive analysis of the thermal and parasitic characteristics of the GaN-based power converter, and the characteristics and design of 3-D integrated magnetic component with heat sink function by finite element software are discussed in detail. Two 90 W, 12-1.8 V, experimental prototype of four-phase interleaving POL converter based ferrite materials and alloy materials on are built and tested, respectively. The experimental results demonstrate that GaN-based power module based on 3-D integrated magnetic component with alloy materials has low parasitic parameters, good thermal performance, high efficiency and high power density than that of ferrite materials.
