Abstract
A digital controller for dc-dc switching converters used in battery-powered handheld devices is introduced. The controller can operate in two modes and encompasses designs of a digital pulse-width modulator (DPWM) and an all-digital pulse-frequency modulator (DPFM). The DPWM has a high resolution and can operate at very-high constant switching frequency (tens of MHz). The DPFM features very-low power consumption, programmable on-time and control over switching frequency range. An experimental FPGA prototype and an application-specific IC that employ controller architecture are built around 3.3 V, 3W, 6 MHz buck power stage and successful operation of the digital controller in both modes is verified. The low power consumption has been also verified on a chip implemented in a standard CMOS 0.18/spl mu/m process.

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
