Purpose: organize a qualified engineering review of an exact DC-DC module.
This record is not a circuit design or installation procedure. Use the exact manufacturer document and applicable system requirements.

System / nominal bus / polarity / reference:
Converter full part number / variant / datasheet revision:
Normal minimum and maximum input at module terminals (V):
Startup and recovery requirement:
Transient amplitude (V), duration (ms), waveform and expected behavior:
External protection and input-filter requirements:
Output voltage (V), current (A) and power (W):
Efficiency at the stated operating point (%):
Estimated input power = output watts / efficiency as a fraction:
Steady input current = input watts / input volts (A):
Dissipation estimate = input watts - output watts (W):
Separate startup / dynamic / source interaction evidence:
Ambient temperature, airflow, direction and enclosure:
Applicable derating curve and temperature measurement point:
Isolation classification / control reference / mechanical variant:
Open items, responsible person and validation evidence:

Fictional example: 66 W / 0.90 = 73.33 W input; 73.33 / 18 = 4.07 A; 73.33 / 48 = 1.53 A; 73.33 - 66 = 7.33 W loss. Efficiency is an invented constant. This excludes startup, distribution and input-filter effects.
