APPLICATIO
the purpose of this LT4430 circuitry is to control and
prevent excessive output voltage overshoot that would
otherwise induce damage or destruction, not to control
power supply timing, sequencing, etc. It is ultimately the
W

U
user’s responsibility to define the acceptance criteria for
any waveforms generated by the power supply relative to
overall system requirements.
