DESIGN CONSIDERATIONS
Š
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,
CSA C22.2 NO. 60950-1 2nd and IEC 60950-1 2nd :
2005 and EN 60950-1 2nd: 2006+A11+A1: 2010, if the
system in which the power module is to be used must
meet safety agency requirements.
A SELV reliability test is conducted on the system
where the module is used to ensure that under a
single fault, hazardous voltage does not appear at
the module’s output.
Do not ground one of the input pins without grounding
one of the output pins. This connection may allow a
non-SELV voltage to appear between the output pin
and ground.
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 fuse with 50A 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.
When the input source is 60 Vdc or below, 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:
Š
The input source must be insulated from any
hazardous voltages, including the ac mains, with
reinforced insulation.
Š
One Vi pin and one Vo pin are grounded, or all the
input and output pins are kept floating.
Š
The input terminals of the module are not operator
accessible.

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, the hiccup mode is default
and latch mode is optional.
For hiccup mode, the module will try to restart after
shutdown. If the overload condition still exists, the
module will shut down again. This restart trial will
continue until the overload 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 Vin (-) terminal. The
switch can be an open collector or open drain.
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-Voltage Protection
The modules include an internal output over-Voltage
protection circuit, which will endure output voltage
limiting. If the output voltage exceeds the OVP set point,
the modules will automatically shut down, the latch
mode is default and the hiccup mode is optional.
For hiccup mode, the module will try to restart after
shutdown. If the overvoltage 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.
Figure 15: Remote on/off implementation
Current Share
The modules can operate in parallel up to 3 units and
provide up to 1600W output power without any or-ing
FET or diode. Between 50% and 100% max load rating,
current–sharing accuracy is +/-2.5%. The equation of
Ishare PIN voltage vs. Io is:
Ishare = 0.25*Io+0.25
Ishare unit is Volt, and Io unit is Amp.
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, the hiccup mode is default
and latch mode is optional.
In parallel application, if the load current is larger than
one module’s full current, the modules can not restart
automatically even in hiccup mode. Either cycling the
input power or toggling the on/off signal for one second
can startup the modules.
For hiccup mode, the module will monitor the module
temperature after shutdown. Once the temperature is
within the specification, the module will be
auto-restarted.
Current Monitor
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.
DS_H48SA53010_08042011
Imon shall sink a current proportional to output current
and reference to Vout (-). This pin can be pulled up
through an external resistor to an external voltage, the
external voltage ranges from 1.5V to Vout (+) +3.3V.
Output current equals Imon×10,000. Accuracy is +/0.5A.

FEATURES DESCRIPTIONS (CON.)
Output Voltage Adjustment (TRIM)
To increase or decrease the output voltage set point,
the modules may be connected with an external
resistor between the TRIM pin and either the Vout (+)
or Vout (-). The TRIM pin should be left open if this
feature is not used.
Figure 17: Circuit configuration for trim-down (decrease output
voltage)
If the external resistor is connected between the TRIM
and Vout (-), the output voltage set point decreases (Fig.
16). The external resistor value required to obtain a
percentage of output voltage change △% is defined as
Figure 16: Circuit configuration for trim-up (increase output
voltage)
If the external resistor is connected between the TRIM
and Vout (+) pins, the output voltage set point
increases (Fig. 15). The external resistor value
required to obtain a percentage of output voltage
change △% is defined as:

When using trim function to increase output voltage, the
output power should increase accordingly. 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 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.
THERMAL CURVES
(WITH HEATSPREADER)
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.
The module’s maximum device temperature is to be defined
and the measured location is illustrated in Figure 19. 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.
