NOTES:
AllparametersmeasuredatTc=25°C,nominalinputvoltage
and full rated load unless otherwise noted. Refer to the
CALEX Application Notes for the definition of terms,
measurementcircuitsandotherinformation.
(7) Dynamic response is the peak overshoot voltage during the
transient response as defined in note 6 above.

(8) Thefunctionaltemperaturerangeisintendedtogiveanadditional
data point for use in evaluating this power supply. At the low
functionaltemperaturethepowersupplywillfunctionwithnoside
effects, however sustained operation at the high functional
temperaturewillreduceexpectedoperationallife.Thedatasheet
specificationsarenotguaranteedoverthefunctionaltemperature
range.
(2) Turn on time is defined as the time from the application of power
until the output is within 1% if its final value.
(3) Determine the correct fuse size by calculating the maximum DC
currentdrainatlowlineinput, maximumload(orusethesupplied
curves) and then adding 20 to 25% to get the desired fuse size.
(9) Thecasethermalimpedanceisspecifiedasthecasetemperature
rise over ambient per package watt dissipated.
(4) Nominimumloadrequired.
(5) Short term stability is specified after a 30 minute warm-up at full
load and with constant line, load and ambient conditions.
(6) The transient response is specified as the time required for the
output to settle from a 100% step load change (rise time of step =
2µ Sec) to a 1% error band.
