Introduction
Introduction
The AEE-10W 12V input dual output series of
switching DC-DC converters is one of the most cost
effective options available in component power. The
series uses an industry standard 1” X 2” package
and pinout configuration, with CNT function avail-
able.
AEE-10W 12V input dual output series uses a 2:1
input range of 9V to 18V, outputs are isolated from
input and the converters are capable of providing
up to 10 watts of output power.
At start up, input current passes through an input fil-
ter designed to help meet CISPR 22 level A radiat-
ed emissions, and Bellcore GR1089 conducted
emissions. A fault clearing device such as a fuse
should be used in line with the input to the module.
The AEE-10W 12V input dual output converters are
pulse width modulated (PWM) and operate at a
nominal fixed frequency of 330 kHz. Feedback to
the PWM controller uses an opto-isolator, maintain-
ing complete isolation between primary and sec-
ondary. Caution should be taken to avoid ground
loops when connecting the converters to ground.

Pin Location
Pin Location
The +Vin and -Vin input connection pins are
located as shown in Figure 1. AEE-10W 12V
input dual output converters have a 2:1 input
voltage range of 9-18V.
Care should be taken to avoid applying
reverse polarity to the input which can dam-
age the converter.

Fusing:
Fusing:
The AEE-10W 12V input dual output power
module has no internal fuse. An external
fuse must always be employed!
To meet international safety requirements, a
250 V olt rated fuse should be used. If one of the
input lines is connected to chassis ground, then
the fuse must be placed in the other input line.
Standard safety agency regulations require
input fusing. Recommended fuse ratings for the
AEE-10W 12Vin dual output is shown in Table1.

oltage Protection
Under installation and cabling conditions where
reverse polarity across the input may occur,
reverse polarity protection is recommended.
Protection can easily be provided as shown in
Figure 2. In both cases the diode rating is deter-
mined by the power of the converter. Diodes
should be rated at 4A/25V for the AEE-10W
12V input dual output series.
Placing the diode across the inputs rather
than in-line with the input offers an advan-
tage in that the diode only conducts in a
reverse polarity condition, which increases
circuit efficiency and thermal performance.
Input Filter

Input filters are included in the converters to
help achieve standard system emissions certifi-
cations. Some users however, may find that
additional input filtering is necessary. The AEE-

of 330 kHz so a high frequency capacitor
mounted close to the input terminals produces
the best results. To reduce reflected noise, a
capacitor can be added across the input as
shown in Figure 3, forming a πfilter. A
47µF/25V electrolytic capacitor is recommend-
ed for C1.
For conditions where EMI is a concern, a differ-
ent input filter can be used. Figure 4 shows an
input filter designed to reduce EMI effects. L1 is
a 12 µH differential inductor, C1 is a 47µF/25V
electrolytic capacitor, and C0 is a 1µF/25V
metal film or ceramic high frequency capacitor.
When a filter inductor L1 is connected in series
with the power converter input, an input capac-
itor C0 should be added. An input capacitor C0
should also be used when the input wiring is
long, since the wiring can act as an inductor.
Failure to use an input capacitor under these
conditions can produce large input voltage
spikes and an unstable output.
Remote On/Of
Remote On/Off Control (optional)
f Control (optional)
The AEE-10W 12V input dual output is negative
logic, remote on/off turns the module off during
a logic high on the remote on/off pin, and turns
the module on during a logic low on the remote
on/off pin.
To turn the power module on or off, the user
must supply a switch to control the voltage on
the remote on/off pin, the switcher may be an
open collector or equivalent (see Fig.5.).
The logic low is Von/off = 0 V to +0.7V.
The logic high is Von/off = +3.6V to +6V.
The module has not internal capacitance to
reduce noise at the on/off pin. Additional capac-
itance is needed. A 1µF/25V electrolytic capac-
itor is recommended for C1.
Input-Output Characteristic
Isolation:
Isolation:
The isolation voltage between input to output,
input to case and case to output are all greater
than 1500 Volt DC. If the system using the
power module needs to meet safety agency
approval, certain rules must be followed in the
design of the system using the module. In par-
ticular, all of the creepage and clearance
requirements of the end-use safety requirement
must be observed. Also specific applications
need to receive other or additional requirements.

Safety Consideration:
Safety Consideration:
For safety-agency approval of the system in
which the power module is used, the power
module must be installed in compliance with the
spacing and separation requirements of the
end-use safety agency standard, i.e., UL1950,
CSA C22.2 No. 950-95, and EN60950. The
input-to-output 1500VDC isolation is an opera-
tional insulation. The DC/DC power module
should be installed in end-use equipment, in
compliance with the requirements of the ulti-
mate application, and is intended to be supplied
by an isolated secondary circuit. When the sup-
ply to the DC/DC power module meets all the
requirements for SELV(<60Vdc), the output is
considered to remain within SELV limits (level
3). If connected to a 60Vdc power system, dou-
ble or reinforced insulation must be provided in
the power supply that isolates the input from
any hazardous voltages, including the ac
mains. One Vi pin and one Vo pin are to be
grounded or both the input and output pins are
to be kept floating. Single fault testing in the
power supply must be performed in combina-
tion with the DC/DC power module to demon-
strate that the output meets the requirement for
SELV. The input pins of the module are not
operator accessible.
Note: Do not ground either of the input pins of
the module, without grounding one of the output
pins. This may allow a non-SELV voltage to
appear between the output pin and ground.

rimming:

Output Over-Current Protection:
Output Over-Current Protection:
AEE-10W 12V input series DC/DC converters
feature foldback current limiting as part of their
Overcurrent Protection (OCP) circuits. When
output current exceeds 110 to 150% of rated
current, such as during a short circuit condition,
the output will shutdown. Note if input voltage
exceeds 20V, the continuous shortcircuit
may damage the module or decrease its life.
Output Filters
Output Filters
When the load is sensitive to ripple and noise,
an output filter can be added to minimize the
effects. A simple output filter to reduce output
ripple and noise can be made by connecting a
capacitor across the output as shown in Figure
6. The recommended value for the output
capacitor is 100µF/25V.
Extra care should be taken when long leads or
traces are used to provide power to the load.
Long lead lengths increase the chance for
noise to appear on the lines. Under these con-
ditions C2 can be added across the load as
shown in Figure 7. The recommended compo-
nent for C2 is 100µF/25V capacitor and con-
necting a 0.47µF/25V ceramic capacitor in par-
allel generally.

Decoupling
Decoupling
Noise on the power distribution system is not
always created by the converter. High speed
analog or digital loads with dynamic power
demands can cause noise to cross the power
inductor back onto the input lines. Noise can be
reduced by decoupling the load. In most cases,
connecting a 10 µF tantalum capacitor in paral-
lel with a 0.1µF ceramic capacitor across the
load will decouple it. The capacitors should be
connected as close to the load as possible.
Ground Loops
Ground Loops
Ground loops occur when different circuits are
given multiple paths to common or earth
ground, as shown in Figure 8. Multiple ground
points can slightly different potential and cause
current flow through the circuit from one point to
another. This can result in additional noise in all
the circuits. To eliminate the problem, circuits
should be designed with a single ground con-
nection as shown in Figure 9.
Parallel Power Distribution
Parallel Power Distribution
Figure 10 shows a typical parallel power distri-
bution design. Such designs, sometimes called
daisy chains, can be used for very low output
currents, but are not normally recommended.
The voltage across loads far from the source
can vary greatly depending on the IR drops
along the leads and changes in the loads clos-
er to the source. Dynamic load conditions
increase the potential problems.
Radial Power Distribution
Radial Power Distribution
Radial power distribution is the preferred
method of providing power to the load. Figure
11. shows how individual loads are connected
directly to the power source. This arrangement
requires additional power leads, but it avoids
the voltage variation problems associated with
the parallel power distribution technique.
Mixed Distribution

In the real world a combination of parallel and
radial power distribution is often used. Dynamic
and high current loads are connected using a

radial design, while static and low current loads
can be connected in parallel. This combined
approach minimizes the drawbacks of a parallel
design when a purely radial design is not feasible.
Redundant Operation
Redundant Operation
A common requirement in high reliability sys-
tems is to provide redundant power supplies.
The easiest way to do this is to place two con-
verters in parallel, providing fault tolerance but
not load sharing. Oring diodes should be used
to ensure that failure of one converter will not
cause failure of the second. Figure 13 shows
such an arrangement. Upon application of
power, one of the converters will provide a
slightly higher output voltage and will support
the full load demand. The second converter will
see a zero load condition and will “idle”. If the
first converter should fail, the second converter
will support the full load. When designing
redundant converter circuits, Shottky diodes
should be used to minimize the forward voltage
drop. The voltage drop across the Shottky
diodes must also be considered when deter-
mining load voltage requirements.

Installation
Installation
Although AEE-10W 12V input dual output
series converters can be mounted in any orien-
tation, free air-flowing must be taken. Normally
power components are always put at the end of
the airflow path or have the separate airflow
paths. This can keep other system equipment
cooler and increase component life spans.
Soldering
Soldering
AEE-10W 12V input dual output series convert-
ers are compatible with standard wave solder-
ing techniques. When wave soldering, the con-
verter pins should be preheated for 20-30 sec-
onds at 110°C, and wave soldered at 260°C for
less than 10 seconds.
When hand soldering, the iron temperature
should be maintained at 425°C and applied to
the converter pins for less than 5 seconds.
Longer exposure can cause internal damage to
the converter. Cleaning can be performed with
cleaning solvent IPA or with water.
MTBF
MTBF
The MTBF, calculated in accordance with
Bellcore TR-NWT-000332 is 3,000,000 hours.
Obtaining this MTBF in practice is entirely pos-
sible. If the ambient air temperature is expected
to exceed +25°C, then we also advise a orient-
ed for the best possible cooling in the air
stream.
ASTEC can offer custom solutions. Please con-
tact the factory for details.
