Reviewing AI-generated PCB power supplies

Check the complete operating envelope

List input extremes, output demand, transients and startup expectations. Distinguish recommended operating conditions from absolute limits. For a linear regulator, check dropout and dissipation at the relevant load; for switching circuits, review the exact device's component and layout requirements.

Verify external components

Check values, tolerances, ratings and the conditions under which the component behaves as assumed. A nominal capacitance or inductor value is not the whole specification. Document the source for every requirement that determines acceptance.

Inspect the board implementation

Trace the power and return loops and compare critical placement with device-specific guidance. Check thermal assumptions and connector current paths. A simulation built from ideal elements does not establish that the physical layout meets the same behavior.

Practical checklist

1. Define input and load conditions.
2. Check the exact device variant.
3. Verify external component requirements.
4. Review power and return paths.
5. Document thermal and startup evidence.

A concrete example

Review an LDO rail for a battery-powered product.

Evidence to accept

The operating envelope, dissipation and required capacitor behavior are checked for the exact part.

Evidence that is insufficient

Only the regulator's maximum advertised current is compared with the load.
