Vec645 Hot Instant

Disconnect the output load. Power the VEC645. If it remains cool (40-50°C), the issue is overload. If it is still hot, the problem is internal or input-related.

By understanding the causes (overload, delta V, poor sinking), implementing the diagnostics (no-load test, thermal imaging), and applying the mitigations (active cooling, via arrays, derating), you can ensure your VEC645 delivers maximum performance without compromising reliability. vec645 hot

Look for hot spots not on the VEC645 itself but surrounding it. A hot inductor nearby suggests output filter issues; a hot PCB trace suggests current crowding. Disconnect the output load
