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)
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 1uF tantalum and 0.01F
ceramic capacitor located 1 inch away from the converter.
(2)
See our application note for picking the correct fuse size.
(3)
The worst case output voltage includes line, load and temperature
effects.
(4)
Dynamic response of the converter will degrade when the SD
series is operated with less than 25% load.
(5)
Short term stability is defined as the drift over 24 hours with
constant line, load and ambient temperature conditions.
(6)
Transient response is specified for a 50 to 75% step load
change. Rise time of step is 2 microseconds.
(7)
Dynamic response is the peak overshoot for a transient as
described in note 6.
(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.
