Isolated DC/DC supplies often fail late, not because the theory is wrong, but because creepage, transformer behavior, feedback drift, and compliance constraints show up when fixes are costly. This episode explains the most common failure modes and the tradeoffs between discrete designs and integrated isolated modules.
