Trans-inductor voltage regulator (TLVR) topologies demand 1:1 coupled inductors that respond instantly to load steps. Our TLVR series pairs a co-fired magnetic body with the 1:1 winding structure AI accelerator power stages need.
AI workloads swing from idle to full load in microseconds. Traditional multiphase buck regulators droop under these transients until the next phase switches in. The TLVR topology — adopted across VR14-class designs for GPUs, CPUs and ASICs — adds a 1:1 secondary winding looped across all phases, letting the regulator respond within a single switching cycle.
The inductor is the heart of that response. A TLVR inductor must deliver:
Our co-fired construction gives TLVR parts a monolithic winding-core body: coupling stays tight, losses stay low, and the part survives the thermal cycling of sustained AI training runs. Output capacitance requirements drop along with transient overshoot — a direct BOM saving for the whole voltage regulator.
