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)
Reduced output power available at 3.5V input. Full output power
is available above 4.6V input. See applications section for more
information.
(2)
Noise is measured per CALEX Application Notes. Measurement
bandwidth is 0-20 MHz for peak-peak measurements, 10 kHz to
1 MHz for RMS measurements. Output noise is measured with
a 0.01F ceramic in parallel with a 1F/35V Tantalum capacitor
located 1" away from the converter to simulate your PCB’s
standard decoupling.
(3)
To determine the correct fuse size, see CALEX Application
Notes.
(4)
Short term stability is specified after a 30 minute warmup
at full load, constant line and recording the drift over a 24
hour period.
(5)
The transient response is specified as the time required to settle
from a 50 to 75 % step load change (rise time of step = 2 Sec)
to a 1% error band.
(6)
Dynamic response is the peak overshoot voltage during the
transient response time as defined in note 5 above.
(7)
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.
(8)
The case thermal impedance is specified as the case
temperature rise over ambient per package watt dissipated.
(9)
No minimum load required for operation . Dynamic regulation
may degrade when run with less than 5% load.
(10) Specifications subject to change without notice.
