Abstract
This work describes a dual-mode mixed-signal peak current-mode controller for high-frequency DC-DC converters. The simple controller provides peak-current protection, inherent low audio susceptibility, and is suitable for portable applications. The voltage feedback loop is implemented using a windowed ADC and a digital PI compensator based on lookup tables. The analog current command used in traditional current-mode controllers is generated by a 2nd order one-bit /spl Delta//spl Sigma/ DAC. The dual-mode controller automatically adjusts the DAC sampling frequency based on the digital error signal magnitude. The mixed-signal control strategy is experimentally verified on a 5V-to-1.5V 1 MHz buck converter prototype that exhibits a settling time of under 50 /spl mu/s.

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
