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.
(1)
See the power derating curve for information on the 12T models
available output power.
(2)
Noise is measured per CALEX application notes. Measurement
bandwidth is 0 - 20 MHz. RMS noise is measured over a 0.01-
1 MHz bandwidth. To simulate standard PCB decoupling
practices, output noise is measured with a 1F, tantalum and
0.01F, ceramic capacitor located 1 inch away from the converter.
Input ripple is measured into a 10H source impedance. Input
Reflected Ripple is for -FT option. For input ripple without the -
FT option see the applications section.
(3)
Optimum performance is obtained when this power supply
is operated within the minimum to maximum load specifications.
(4)
Output regulation is specified by simultaneously changing all
outputs from minimum to maximum load and noting the change
in each output.
(5)
Cross regulation is defined as the change in one output when
only one of the other outputs is changed from maximum to
minimum load.
(6)
Short term stability is specified after a 30 minute warm up at full
load, constant line, load and ambient conditions.
(7)
Transient response is defined as the time for the output to settle
from a 50 to 75% step load change to a 1% error band (rise time
of step = 2s).
(8)
Dynamic response is defined as the peak overshoot during
a transient as defined in note 7 above.
(9)
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. Sustained operation at the high functional
temperature will reduce the expected operational life. The data
sheet specifications are not guaranteed over the functional
temperature range.
(10) The case thermal impedance is specified as the case temperature
rise over ambient per package watt dissipated.
(11) Specifications subject to change without notice.
