8.5 Watt UW Triple Series DC/DC Converters
Description
Features
n
The 8.5 Watt Triple Output DC/DC converters are ideal for
wide(4:1)inputrangeapplications.Theseunitsareparticularly
well suited for solar powered RTUs and instruments.
Wide 4:1 Input Voltage Range (9-36 or 18-72VDC)
n
Triple Low Noise, Highly Regulated Outputs
n
Efficiency 70% for All Line Conditions
They are designed with a high accuracy feedback control
circuit and coupled inductor magnetics. Each converter has
both a logic shut down pin and thermal overload protection
circuitry. All outputs and the power switch are overvoltage
protected.
n
No Derating to 80°C Case Temperature
n
Six-Sided Shielded Low Thermal
Gradient Copper Case
n
These converters are encased in a six-sided, completely
shielded copper case. The UW Triple Series is covered under
the CALEX 5 Year Warranty.

NOTES:
(7) The input ripple rejection is specified for DC to 120Hz ripple with
a modulation amplitude of 1% Vin.
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,
measurementcircuitsandotherinformation.
*
(8) For module protection only, see also note 2.
(9) The logic shutdown pin is Open Collector TTL, CMOS, and relay
compatible. The input to this pin is referenced to input minus.
(2) Determine the correct fuse size by calculating the maximum DC
currentdrainatlowlineinput, maximumload andthenadding20
to 25 percent.
(10) Thefunctionaltemperaturerangeisintendedtogiveanadditional
data point for use in evaluating this power supply. At the low
functionaltemperaturethepowersupplywillfunctionwithnoside
effects, however, sustained operation at the high functional
temperaturewillreduceexpectedoperationallife. Thedatasheet
specificationsarenotguaranteedoverthefunctionaltemperature
range.
(3) Themodulewillnotbedamagedifrunatlessthanminimumload.
Regulation can degrade with less than minium load or substatial
loadimbalance.

(4) Short term stability is specified after a 30 minute warm-up at full
load, and with constant line, load and ambient conditions.
(11) Thecasethermalimpedanceisspecifiedasthecasetemperature
rise over ambient per package watt dissipated.
(5) The transient response is specified as the time required to settle
from 25 to 75% step load change (rise time of step = 2µ Sec.) to
a 1% error band.
(6) Dynamic response is the peak overshoot voltage during the
transient response time defined in note 5 above.
