To meet the high and fluctuating power demand of ASICs, a state-of-the-art technique, trans-inductor voltage regulator (TLVR) has been proposed. However, this TLVR requires a compensation inductor in series with the secondary winding of its inductor/transformer to produce an additional coupling current to achieve a fast transient response. Therefore, the TLVR needs additional layout space and the compensation inductor imposes additional cost and power loss. This disclosure describes a magnetic integrated trans-inductor voltage regulator (MITLVR) that integrates the transformer and the compensation inductor into a magnetic component. This topology can achieve ultra-fast transient performance as TLVR but without an additional magnetic component in series with secondary winding. It provides a higher power density and cost-saving solution compared with existing TLVR and is suitable for xPU applications.
