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.
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 10μF tantalum and 0.01μF
ceramic capacitor located 1 inch away from the converter. Input
ripple is measured into a 10μH source impedance.
See our application note for picking the correct fuse size.
The converter may be safely operated at any load from zero to
the full rating. Dynamic response of the converter may degrade
if the converter is operated with less than 25% output load.
Load regulation is defined for loading/unloading both outputs
simultaneously. Load range is 25 to 100%.

(5)
Cross regulation is defined for loading/unloading one output
while the other output is kept at full load. Load range is
25 to 100%.
Short term stability is specified after a 30 minute warmup
at full load, constant line and recording the drift over a 24
hour period.
Case is tied to the CMN output pin.
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 may reduce the expected operational
life. The data sheet specifications are not guaranteed over
the functional temperature range.
The case thermal impedance is specified as the case temperature
rise over ambient per package watt dissipated.
(10) Specifications subject to change without notice.
