Applications Information
General Information
The 20 Watt NT Single series is also mindful of battery
operation for industrial, medical control and remote data
collection applications. The remote ON/OFF pin places the
converter in a very low power mode that draws typically less
than 3 mA from the input source.
Full overload protection is provided by independent pulse-by-
pulse current limiting and an over-temperature shutdown
circuit. These protection features assure you that our 20 Watt
single will provide zero failure rate operation.
A fully five-sided shielded, sealed, water washable case is
standard along with specified operation over the full industrial
temperature range of -40 to +90°C.

your PCB’s standard decoupling. Input reflected ripple is measured
into a 10H source impedance.
(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 input ripple rejection is specified for DC to 120 Hz ripple with
a modulation amplitude of 1% of Vin.
(8)
The Case is tied to the -IN pin.
(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, 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) The case thermal impedance is specified as the case
temperature rise over ambient per package watt dissipated.
(11) Specifications subject to change without notice.
