Close the rail loss and shelf transient on separate boundaries — stated inputs
Rail: 0.80 V at 2,000 A; hot path 20 µΩ; step 1,000 A in 1.0 µs; loop inductance 10 pH; incremental droop budget 40 mV. Shelf: output 120 kW, efficiency 96%, input limit 125 kW; extra load 20 kW for 10 ms; capacitor window 50→46 V.modeled
| Value kind | modeled — Interpret this value according to its displayed kind, scope, source, and as-of date. |
|---|---|
| Scope | Separate rail and shelf boundaries. Unsupported sensitivities and rationale are in the opening callout; Chapter 4.7 owns the interface. Ideal screens exclude component tolerance, aging and dynamic validation. |
