NOTES:
*
All parameters measured at Tc= 25° C, nominal input voltage
and full rated load unless otherwise noted. Refer to the
CALEX Application Notes for the definition of terms,
measurement circuits and other information.
(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
current drain at low line input, maximum load (or use the supplied
curves) and then adding 20 to 25% to get the desired fuse size.
(4)
No minimum load required.
(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
= 2 Sec) to a 1% error band.
(7)
Dynamic response is the peak overshoot voltage during the
transient response as defined in note 6 above.
(8)
The functional temperature range is intended to give an additional
data point for use in evaluating this power supply. At the low
functional temperature the power supply will function with no
side effects, however sustained operation at the high functional
temperature will reduce expected operational life. The data
sheet specifications are not guaranteed over the functional
temperature range.
(9)
The case thermal impedance is specified as the case temperature
rise over ambient per package watt dissipated.
