Abstract
A trans-inductor voltage regulator (TLVR) circuit has multiple phases and a switching circuit for each phase. Each switching circuit has a winding of a transformer as an output inductor. The other windings of the transformers are connected in series with a nonlinear compensation inductor. An on-time period of each switching circuit is reduced when a load transient condition occurs or when a load current starts to be stable after the load transient condition.
