A 10 MHz mixed-signal CPM controlled DC-DC converter IC with novel gate swing circuit and instantaneous efficiency optimization
Bibliographic record
Abstract
This paper introduces a mixed-signal peak current-programmed mode controlled 10 MHz dc-dc converter integrated circuit (IC) for low-power applications. The IC combines segmented power transistors, gate drivers and the main functional blocks of a multi-mode controller. Based on the information about the peak transistor current, obtained from the voltage loop, the controller instantaneously changes the number of segments, gate drive voltage, or switches to pulse-frequency modulation, such that for each operating point efficiency is optimized. To obtain reliable operation at such a high switching frequency and achieve efficiency optimization novel architecture of gate swing circuit is combined with modifications of known designs of other functional blocks. Experimental verification of a 0.6 W buck converter IC, fabricated in a 0.13 μm process, demonstrate the peak efficiency of an 83%, near time-optimal dynamic response, and up to a 20% efficiency improvement due to the action of the efficiency optimization controller.

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.
