Description
The versatile 5 Watt Dual Output converter is particularly
suitable for use in microprocessor systems where 5 Volts is
the primary power source, and where a low noise plus and
minus output voltage is required.
The shielded transformer provides low I/O capacitance
and high common mode input to output isolation.
The low guaranteed output noise of 20mV P-P maximum is
achieved by a built-in linear post regulator.
Available in standard 6 sided shielding, or the -5 model
which has 5 sided shielding and is water washable.
Each converter is completely specified, fully ATE tested,
contains overload protection, and is covered under CALEX's
5 year warranty.

NOTES:
*
All parameters measured at Tc=25 C, nominal 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)
To determine the correct fuse size, see CALEX Application
Notes.
(2)
No minimum load current is required.
(3)
Short term stability is specified after a 30 minute warm-up at full
load, and with constant line, load and ambient conditions.
(4)
The transient response is specified as the time required to settle
from 100% step load change (rise time of step = 2Sec.) to a 1%
error band.
(5)
Dynamic response is the peak overshoot voltage during the
transient response time defined in note 4 above.
(6)
Limited to 10 seconds maximum when both outputs are shorted
to Common at the same time.
(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 may reduce expected operational life. All 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)
Water Washability - Calex DC/DC converters are designed to
withstand most solder/wash processes. Careful attention should
be used when assessing the applicability in your specific
manufacturing process. Converters are not hermetically sealed.

Case
The 5D12.185B, 5D15.150B and 5D15.167B use a six sided
shielded copper case system. It is filled with a silicon rubber
compound and the outside is painted black. The seal around
the terminals is not hermetic and the unit should not be
immersed in any liquid.
The 5D12.185B-5, 5D15.150B-5 and 5D15.167B-5 use a
5 sided shielded steel case system. The case is specially tin
plated to deter rusting. The assembly is filled with a compound
which seals it and will withstand water washing in the typical
manufacturing cleaning process.
Typical Performance (Tc=25C; Full Rated Load).
