NOTES:
(1)
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.
(2)
Output Noise is measured with a 1F tantalum capacitor and a
0.01F ceramic capacitor across the output. The fundamental
component of noise is at the switching frequency and also is
commonly referred to as ripple.
(3)
External fusing should be used for system protection due to a
catastrophic failure. See CALEX Application Note 9 in the Calex
DC/DC Catalog to determine correct fuse.
(4)
Load Transient Overshoot is the output voltage peak amplitude
referenced to the final value due to a step load change of 50-75%
occurring only on the measured output. “Load Transient
Overshoot” and “Dynamic Response” are the same specification.
Load Transient Recovery Time is the time for the output to return
to within specified voltage error band centered about the final
value. “Load Transient Recovery Time” and “ Transient Response”
are the same specification.
(5)
Temperature coefficient is defined for case temperatures. Output
voltage deviation is calculated as the maximum resulting from
either 1) 25°C case to maximum operating case temperature, or
2) 25°C case to minimum operating case temperature.
(6)
Below the minimum rated load, the output may exhibit noise
performance degradation. Operation with less than minimum
rated load will not damage the unit, and the DC regulation is not
significantly affected.
(7)
Water washable units will not be damaged by a water wash
process. However, they are not hermetically sealed.
(8)
The case thermal impedance is specified and the case
temperature rise over ambient per package watt dissipated.
(9)
Case functional temperature range is intended to give an
additional data point for use is 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.
(10) Specifications subject to change without notice.
