REQ-P-01 — The output voltage at any of the seven selectable levels shall remain within ±5 % of the nominal target voltage across the full load range of 10 % to 100 % of rated output power. Verified by load sweep on physical hardware; simulation at 56 V shows ±open-loop offset (closed-loop sim pending LM5156 PSpice model).

The output voltage at any of the seven selectable levels shall remain within ±5 % of the nominal target voltage across the full load range of 10 % to 100 % of rated output power. Verified by load sweep on physical hardware; simulation at 56 V shows ±open-loop offset (closed-loop sim pending LM5156 PSpice model).

Load sweep from 10 % to 100 % of rated load in steps of 10 % at each of the 7 output voltages. Output voltage shall remain within ±5 % of nominal at every load step. Note: open-loop simulation shows ~5 V offset at 56 V — hardware verification required.
