Abstract
This paper introduces a multiphase high step-down DC-DC converter that is suitable for voltage regulator module (VRM) applications. In particular, this converter is derived from the conventional flying capacitor multilevel converter. Despite being a multiphase topology, the converter contains just a single flying capacitor that reduces voltage swing at the inductor switching nodes. Furthermore, all switches experience a maximum voltage stress of half the input voltage providing benefits such as the use of transistors with better figures of merit (FOM), as well as reduced switching losses. The converter is well suited for high conversion ratios and high load output required by VRMs as the freewheeling path of each phase contains only one switch. The effectiveness of this topology is verified with an experimental prototype with wide input voltage 12V/24V, and load V <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">out</sub> = 1.2 V, I <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">out</sub> ≤ 40 A operating at 500 kHz switching frequency. Peak efficiencies of 93.2% at 16A, and 89.4% at 28A, are attained with inputs at 12 V and 24V, respectively.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

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
