Summary:This paper proposes an inverted pyramid trans-inductor voltage regulator (IP-TLVR) converter that can offer significant benefits, including extended duty cycle, reduced power loss, and lower voltage stress. Additionally, it exhibits superior transient performance without additional complex controls by using trans-inductor (TL). This architecture has two inductor current outputs, which greatly increase the power density. This topology features allow the inductor current to be auto-balanced. It is manufactured using a 0.18\mu \mathrm{m} BCD process, which achieves a peak efficiency of 93.6%, a maximum output current of 100A, and attains an 8\mu \mathrm{s} recovery time for a 90\mathrm{A}/1\mu \mathrm{s} load transition.
