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 150μF electrolytic capacitor (ESR <
0.7 Ω at 100 kHz) mounted close to the input of the
module to improve the stability.

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,
CSA C22.2 NO. 60950-1 2nd and IEC 60950-1 2nd :
2005 and EN 60950-1 2nd: 2006+A11+A1: 2010,
GB 4943.1: 2011, 5000m if the system in which the
power module is to be used must meet safety agency
requirements.
reinforce insulation based on 110 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
hazardous voltage.
Basic insulation based on 110Vdc input is provided
between the input and the accessible metal of the module
when the accessible metal is grounding.
for the module’s output to meet SELV requirements,
so we only used the function insulation between output
and the accessible metal of the module
all of the following must be met:

The input source must be insulated from the ac
mains by reinforced or double insulation.

The input terminals of the module are not operator
accessible.

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.
E-mail: DCDC@delta.com.tw
http://www.deltaww.com/dcdc
P5
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.
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.
.
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 to floating.
Figure 14: Remote on/off implementation
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 shut down, and will try to restart after
shutdown(hiccup mode). If the overload condition still
exists, the module will shut down again. This restart trial
will continue until the overload condition is corrected.
Over-Voltage Protection
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 protection circuit will constrain the max
duty cycle to limit the output voltage, if the output
voltage continuously increases the modules will shut
down, and then restart after a hiccup-time (hiccup
mode).
Over-Temperature Protection
The over-temperature protection consists of circuitry
that provides protection from thermal damage. If the
module will shut down.The module will restart after the
temperature is within specification
DS_HA1SV120004PRFA_02122014
Output Voltage Adjustment (TRIM)
To increase or decrease the output voltage set point,
connect an external resistor between the TRIM pin and
SENSE(+) pin or SENSE(-) pin. The TRIM pin should be
left open if this feature is not used.
For trim down, the external resistor value required to
obtain a percentage of output voltage change △% is
defined as:
 10 *Vnom * (1 − ∆ ) 
Rtrim − down = 
 ( KΩ )
Vnom − Vnom * (1 − ∆ ) 
Ex. When Trim-down -10% (12V×0.9=10.8V)
 10 *12 * 0.9 
Rtrim − down = 
 (KΩ ) = 90(KΩ )
12 − 12 * 0.9 
For trim up, the external resistor value required to obtain
a percentage output voltage change △% is defined as:
Rtrim − up =
Vnom * 7.92(1 + ∆)
KΩ
Vnom *(1 + ∆)* 0.208 − 2.5
Ex. When Trim-up +10% (12V×1.1=13.2V)
Rtrim − up =
12 × 7.92 × (1 + 0.1)
= 419(KΩ )
12 *(1 + 0.1)* 0.208 − 2.5
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.

THERMAL CONSIDERATIONS
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.
Pin function
The pin was difine as follow in figure 20 ,we will explain
the pin function:
+IN, -IN .DC voltage inputs.
Gate IN . The Gate IN pin on a driver module may be
used as a logic enable/disable input.When Gate IN is pull
low (<1V,referenced to –Vin ),the module is turned off .
when Gate IN is floating (open collector) ,the module is
turned on .The open circuit voltage of Gate in PIN is less
than 5V.
Gate OUT . the pulsed signal at the Gate OUT pin of a
regulating driver module is used to synchronously drive
the surge circuit in order to meet the IRA12 surge
needed. If you don’t used this function, please floating it.
+OUT, -OUT .DC voltage outputs.
T(TRIM). Provides fixed or variable adjustment of the
module output.
Trimming down. Allows output voltage of the module to
be trimmed down, with a decrease in efficiency .ripple as
a percent of output voltage goes up and input range
widens since input voltage dropout(loss of regulation)
moves down
Trimming up. Reverses the above effects.
-Sense,+Sense.Provides for locating the point of optimal
voltage regulation external to the converter.
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’’).

Thermal Derating
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.
