SFFS410 July 2022 LM73605
The failure mode distribution estimation for the LM73605 in Table 3-1 comes from the combination of common failure modes listed in standards such as IEC 61508 and ISO 26262, the ratio of sub-circuit function size and complexity, and from best engineering judgment.
The failure modes listed in this section reflect random failure events and do not include failures resulting from misuse or overstress.
| Die Failure Modes | Failure Mode Distribution (%) |
|---|---|
| SW not switching, output stuck on | 10 |
| SW not switching, no output | 20 |
| SW switching, out of specification voltage or timing | 60 |
| Power Good – False Trip or Failure to Trip | 5 |
| Short circuit any two pins | 5 |
