DESIGN CONSIDERATIONS
Input Source Impedance
The impedance of the input source connecting to the
DC/DC power modules will interact with the modules and
affect the stability. A low ac-impedance input source is
recommended. If the source inductance is more than a
few µH, we advise adding a 10 to 100 µF electrolytic
capacitor (ESR < 0.7 Ω at 100 kHz) mounted close to the
input of the module to improve the stability.
Layout and EMC Considerations
Delta’s DC/DC power modules are designed to operate in
a wide variety of systems and applications. For design
assistance with EMC compliance and related PWB layout
issues, please contact Delta’s technical support team. An
external input filter module is available for easier EMC
compliance design.
Application notes to assist
designers in addressing these issues are pending
release.
Safety Considerations
The power module must be installed in compliance with
the spacing and separation requirements of the
end-user’s safety agency standard, i.e., UL60950-1,
CAN/CSA-C22.2, No. 60950-1 and EN60950-1+A11 and
IEC60950-1, if the system in which the power module is to
be used must meet safety agency requirements.
Basic insulation based on 75 Vdc input is provided
between the input and output of the module for the purpose
of applying insulation requirements when the input to this
DC-to-DC converter is identified as TNV-2 or SELV. An
additional evaluation is needed if the source is other than
TNV-2 or SELV.
When the input source is SELV circuit, the power module
meets SELV (safety extra-low voltage) requirements. If the
input source is a hazardous voltage which is greater than
60 Vdc and less than or equal to 75 Vdc, for the module’s
output to meet SELV requirements, all of the following
must be met:
DS_ V36SE12004_12252012
Š
The input source must be insulated from the ac
mains by reinforced or double insulation.
Š
The input terminals of the module are not operator
accessible.
Š
If the metal baseplate is grounded, one Vi pin and
one Vo pin shall also be grounded.
Š
A SELV reliability test is conducted on the system
where the module is used, in combination with the
module, to ensure that under a single fault,
hazardous voltage does not appear at the module’s
output.
When installed into a Class II equipment (without
grounding), spacing consideration should be given to
the end-use installation, as the spacing between the
module and mounting surface have not been evaluated.
The power module has extra-low voltage (ELV) outputs
when all inputs are ELV.
This power module is not internally fused. To achieve
optimum safety and system protection, an input line fuse
is highly recommended. The safety agencies require a
normal-blow fuse with 5A maximum rating to be installed
in the ungrounded lead. A lower rated fuse can be used
based on the maximum inrush transient energy and
maximum input current.
Soldering and Cleaning Considerations
Post solder cleaning is usually the final board assembly
process before the board or system undergoes electrical
testing. Inadequate cleaning and/or drying may lower the
reliability of a power module and severely affect the
finished circuit board assembly test. Adequate cleaning
and/or drying is especially important for un-encapsulated
and/or open frame type power modules. For assistance
on appropriate soldering and cleaning procedures,
please contact Delta’s technical support team.

FEATURES DESCRIPTIONS
Over-Current Protection
The modules include an internal output over-current
protection circuit, which will endure current limiting for an
unlimited duration during output overload. If the output
current exceeds the OCP set point, the modules will
automatically shut down, and enter hiccup mode or latch
mode, which is optional.
For hiccup mode, the module will try to restart after
shutdown. If the over current condition still exists, the
module will shut down again. This restart trial will continue
until the over-current condition is corrected.
Remote On/Off
The remote on/off feature on the module can be either
negative or positive logic. Negative logic turns the
module on during a logic low and off during a logic high.
Positive logic turns the modules on during a logic high
and off during a logic low.
Remote on/off can be controlled by an external switch
between the on/off terminal and the Vi(-) terminal. The
switch can be an open collector or open drain.
For negative logic if the remote on/off feature is not
used, please short the on/off pin to Vi(-). For positive
logic if the remote on/off feature is not used, please
leave the on/off pin floating.
For latch mode, the module will latch off once it shutdown.
The latch is reset by either cycling the input power or by
toggling the on/off signal for one second.
Vi(+)
Vo(+)
Sense(+)
Over-Voltage Protection
ON/OFF
The modules include an internal output over-voltage
protection circuit, which monitors the voltage on the output
terminals. If this voltage exceeds the over-voltage set point,
the module will shut down, and enter in hiccup mode or
latch mode, which is optional.
For hiccup mode, the module will try to restart after
shutdown. If the over voltage condition still exists, the
module will shut down again. This restart trial will continue
until the over-voltage condition is corrected.
For latch mode, the module will latch off once it shutdown.
The latch is reset by either cycling the input power or by
toggling the on/off signal for one second.
Over-Temperature Protection
The over-temperature protection consists of circuitry that
provides protection from thermal damage. If the
temperature exceeds the over-temperature threshold the
module will shut down, and enter in hiccup mode or latch
mode, which is optional.
Sense(-)
Vi(-)
Figure 14: Remote on/off implementation
Remote Sense
Remote sense compensates for voltage drops on the
output by sensing the actual output voltage at the point
of load. The voltage between the remote sense pins
and the output terminals must not exceed the output
voltage sense range given here:
[Vo(+) – Vo(–)] – [SENSE(+) – SENSE(–)] ≤ 10% × Vout
This limit includes any increase in voltage due to
remote sense compensation and output voltage set
point adjustment (trim).
For hiccup mode, the module will try to restart after
shutdown. If the over temperature condition still exists, the
module will shut down again. This restart trial will continue
until the over-temperature condition is corrected.
For latch mode, the module will latch off once it shutdown.
The latch is reset by either cycling the input power or by
toggling the on/off signal for one second.

FEATURES DESCRIPTIONS (CON.)
If the remote sense feature is not used to regulate the output
at the point of load, please connect SENSE(+) to Vo(+) and
SENSE(–) to Vo(–) at the module.
The output voltage can be increased by both the remote
sense and the trim; however, the maximum increase is the
larger of either the remote sense or the trim, not the sum of
both.
When using remote sense and trim, the output voltage
of the module is usually increased, which increases the
power output of the module with the same output
current.
Care should be taken to ensure that the maximum
output power does not exceed the maximum rated
power.
Output Voltage Adjustment (TRIM)
To increase or decrease the output voltage set point,
connect an external resistor between the TRIM pin and
either the SENSE(+) or SENSE(-). The TRIM pin
should be left open if this feature is not used.
Figure 17: Circuit configuration for trim-up (increase output
voltage)
If the external resistor is connected between the TRIM
and SENSE (+) the output voltage set point increases
(Fig. 19). The external resistor value required to obtain
a percentage output voltage change △% is defined as:
Rtrim − up =
5 . 11 Vo (100 + ∆ ) 511
−
− 10 . 2 (K Ω )
1.225 ∆

Ex. When Trim-up +10% (12V×1.1=13.2V)

5.11 × 12 × (100 + 10) 511
−
− 10.2 = 489.3(KΩ )
1.225 × 10
10
The output voltage can be increased by both the remote
sense and the trim, however the maximum increase is
the larger of either the remote sense or the trim, not the
sum of both.
Figure 16: Circuit configuration for trim-down (decrease
output voltage)
If the external resistor is connected between the TRIM
and SENSE (-) pins, the output voltage set point
decreases (Fig. 18). The external resistor value
required to obtain a percentage of output voltage
change △% is defined as:
When using remote sense and trim, the output voltage
of the module is usually increased, which increases the
power output of the module with the same output
current.
Care should be taken to ensure that the maximum
output power of the module remains at or below the
maximum rated power.

THERMAL CONSIDERATIONS
THERMAL CURVES
Thermal management is an important part of the system
design. To ensure proper, reliable operation, sufficient
cooling of the power module is needed over the entire
temperature range of the module. Convection cooling is
usually the dominant mode of heat transfer.
Hence, the choice of equipment to characterize the
thermal performance of the power module is a wind
tunnel.
Thermal Testing Setup
Delta’s DC/DC power modules are characterized in
heated vertical wind tunnels that simulate the thermal
environments encountered in most electronics
equipment. This type of equipment commonly uses
vertically mounted circuit cards in cabinet racks in which
the power modules are mounted.
The following figure shows the wind tunnel
characterization setup. The power module is mounted
on a test PWB and is vertically positioned within the
wind tunnel. The space between the neighboring PWB
and the top of the power module is constantly kept at
6.35mm (0.25’’).

Heat can be removed by increasing airflow over the
module. To enhance system reliability, the power
module should always be operated below the maximum
operating temperature. If the temperature exceeds the
maximum module temperature, reliability of the unit may
be affected.
