Multiphase optimal response mixed-signal current-programmed mode controller
Bibliographic record
Abstract
This paper presents a simple and practical implementation of a proximity optimal-time (OT) response controller for multiphase interleaved dc-dc switch-mode power supplies (SMPS). This novel solution enables equal current sharing between phases not only in steady state, but also during load transients. It also achieves a bump-less transition between the transient and steady state, where the interleaved operation is resumed without any delay. To minimize calculation burden and hardware complexity, a single digital voltage loop and multiple analog current loops are combined to implement a capacitor-charge balance based optimal-time recovery algorithm. The interface between the loops is provided through a structure consisting of a sample-and-hold circuit (S&H) and a relatively slow successive approximation digital-to-analog converter (DAC) providing control signals for all the current loops. The effectiveness of the controller is demonstrated on a 2-phase, 5 V-to-1.8 V, 20 W, interleaved buck converter operating at a 1 MHz switching frequency. The experimental results verify equal current sharing under all operating conditions, bump-less transition between the modes, and demonstrate that upon a transient converter reaches new steady state in the virtually fastest possible time.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
