Abstract
This paper addresses the effect of the gate driving capability on the efficiency of synchronous buck converters. To reduce the switching loss in DC-DC converters, the gate drivers are often designed to turn the power MOSFETs on/off as quickly as possible. However, for fast turn on/off, gate drivers with high driving capability and consequently high power consumption are required. Since the gate driver power consumption is independent of the load, the gate driver power consumption at light load could become a large portion of the total power loss. In this paper, a segmented gate driver with adjustable driving capability is proposed. This allows the optimization of the power conversion efficiency as a function of the loading condition. The results of this work shows an improvement in efficiency of up to 7% under light load condition with a significant reduction in ringing and overshoot at the switching node and at the gate terminals of output stage transistors.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
