REQ-P-04 — The boost stage shall implement cycle-by-cycle current limiting with a peak current limit of 10 A (set by LM5156 internal threshold). On a persistent output fault (e.g. short circuit), the controller shall enter hiccup mode — repeatedly attempting restart — rather than sustaining a high fault current. Verified behaviourally in LTspice v7 simulation.

Statement
The boost stage shall implement cycle-by-cycle current limiting with a peak current limit of 10 A (set by LM5156 internal threshold). On a persistent output fault (e.g. short circuit), the controller shall enter hiccup mode — repeatedly attempting restart — rather than sustaining a high fault current. Verified behaviourally in LTspice v7 simulation.
Acceptance Criteria
Short the output terminals with unit running. No component damage shall occur. Confirm inductor peak current does not exceed 10 A (LM5156 OC limit). Confirm hiccup/retry behaviour on sustained short. Remove short — unit shall recover without reset.
