Description
The EQW series, Eighth-brick power modules are isolated dc-dc converters that can deliver up to 6A of output
current and provide a precisely regulated output voltage of 12Vdc over a wide range of input voltages (Vi = 36 75Vdc). The modules achieve full load efficiency of 91.5% at 12Vdc output voltage. The open frame modules
construction, available in both surface-mount and through-hole packaging, enable designers to develop cost- and
space-efficient solutions. Standard features include remote On/Off, remote sense, output voltage adjustment, over
voltage, over current and over temperature protection.

CAUTION: This power module is not internally fused. An input line fuse must always be used.
This power module can be used in a wide variety of applications, ranging from simple standalone operation to an
integrated part of sophisticated power architectures. To preserve maximum flexibility, internal fusing is not included,
however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies
require a time-delay fuse with a maximum rating of 6 A (see Safety Considerations section). Based on the
information provided in this data sheet on inrush energy and maximum dc input current, the same type of fuse with a
lower rating can be used. Refer to the fuse manufacturer’s data sheet for further information.

Safety Considerations
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., UL60950, CSA C22.2 No. 60950-00
and VDE 0805:2001-12 (IEC60950, 3rd Ed).
These converters have been evaluated to the spacing
requirements for Basic Insulation, per the above
safety standards; and 1500 Vdc is applied from Vi to
Vo to 100% of outgoing production.
For all input voltages, other than DC MAINS, where
the input voltage is less than 60V dc, if the input
meets all of the requirements for SELV, then:
•
The output may be considered SELV. Output
voltages will remain within SELV limits even with
internally-generated non-SELV voltages. Single
component failure and fault tests were performed
in the power converters.
•
One pole of the input and one pole of the output
are to be grounded, or both circuits are to be kept
floating, to maintain the output voltage to ground
voltage within ELV or SELV limits.
For all input sources, other than DC MAINS, where
the input voltage is between 60 and 75V dc
(Classified as TNV-2 in Europe), the following must
be adhered to, if the converter’s output is to be
evaluated for SELV:
•
The input source is to be provided with reinforced
insulation from any hazardous voltage, including
the AC mains.
•
One Vi pin and one Vo pin are to be reliably
earthed, or both the input and output pins are to
be kept floating.
•
Another SELV reliability test is conducted on the
whole system, as required by the safety
agencies, on the combination of supply source
and the subject module to verify that under a
single fault, hazardous voltages do not appear at
the module’s output.
The power module has ELV (extra-low voltage)
outputs when all inputs are ELV.
All flammable materials used in the manufacturing of
these modules are rated 94V-0, and UL60950 A.2 for
reduced thickness. The input to these units is to be
provided with a maximum 6A time- delay in the
unearthed lead.

Feature Description
Remote On/Off
Two remote on/off options are available. Positive logic
turns the module on during a logic high voltage on the
ON/OFF pin, and off during a logic low. Negative logic
remote On/Off, device code suffix “1”, turns the
module off during a logic high and on during a logic
low.
Vin+
The amount of power delivered by the module is
defined as the voltage at the output terminals
multiplied by the output current. When using remote
sense and trim, the output voltage of the module can
be increased, which at the same output current would
increase the power output of the module. Care should
be taken to ensure that the maximum output power of
the module remains at or below the maximum rated
power (Maximum rated power = Vo,set x Io,max).

Figure 10. Remote On/Off Implementation.
To turn the power module on and off, the user must
supply a switch (open collector or equivalent) to
control the voltage (Von/off) between the ON/OFF
terminal and the VIN(-) terminal (see Figure 10). Logic
low is 0V ≤ Von/off ≤ 1.2V. The maximum Ion/off during a
logic low is 1mA, the switch should be maintain a
logic low level whilst sinking this current.
During a logic high, the typical maximum Von/off
generated by the module is 15V, and the maximum
allowable leakage current at Von/off = 5V is 1μA.
If not using the remote on/off feature:
For positive logic, leave the ON/OFF pin open.
For negative logic, short the ON/OFF pin to VIN(-).
Remote Sense
Remote sense minimizes the effects of distribution
losses by regulating the voltage at the remote-sense
connections (See Figure 11). The voltage between
the remote-sense pins and the output terminals must
not exceed the output voltage sense range given in
the Feature Specifications table:
[VO(+) – VO(–)] – [SENSE(+) – SENSE(–)] ≤ 0.5 V
Although the output voltage can be increased by both
the remote sense and by the trim, the maximum
increase for the output voltage is not the sum of both.
The maximum increase is the larger of either the
remote sense or the trim.
LINEAGE POWER
At input voltages below the input undervoltage lockout
limit, the module operation is disabled. The module
will only begin to operate once the input voltage is
raised above the undervoltage lockout turn-on
threshold, VUV/ON.
Once operating, the module will continue to operate
until the input voltage is taken below the undervoltage
turn-off threshold, VUV/OFF.
Overtemperature Protection
To provide protection under certain fault conditions,
the unit is equipped with a thermal shutdown circuit.
The unit will shutdown if the thermal reference point
Tref (Figure 14), exceeds 110oC (typical), but the
thermal shutdown is not intended as a guarantee that
the unit will survive temperatures beyond its rating.
The module will automatically restarts after it cools
down.
Output Overvoltage Protection
The output overvoltage protection consists of circuitry
that internally clamps the output voltage. If a more
accurate output overvoltage protection scheme is
required then this should be implemented externally
via use of the remote on/off pin.

Output Voltage Programming
Trimming allows the output voltage set point to be
increased or decreased, this is accomplished by
connecting an external resistor between the TRIM pin
and either the VO(+) pin or the VO(-) pin (COM pin) .
VIN(+)
Connecting an external resistor (Rtrim-up) between the
TRIM pin and the VO(+) (or Sense (+)) pin increases
the output voltage set point. The following equations
determine the required external resistor value to
obtain a percentage output voltage change of Δ%:

Connecting an external resistor (Rtrim-down) between

decreases the output voltage set point. To maintain
set point accuracy, the trim resistor tolerance should
be ±0.1%.

The voltage between the Vo(+) and Vo(–) terminals
must not exceed the minimum output overvoltage
protection value shown in the Feature Specifications
table. This limit includes any increase in voltage due
to remote-sense compensation and output voltage
set-point adjustment trim.
Although the output voltage can be increased by both
the remote sense and by the trim, the maximum
increase for the output voltage is not the sum of both.
The maximum increase is the larger of either the
remote sense or the trim. The amount of power
delivered by the module is defined as the voltage at
the output terminals multiplied by the output current.
When using remote sense and trim, the output
voltage of the module can be increased, which at the
same output current would increase the power output
of the module. Care should be taken to ensure that
the maximum output power of the module remains at
or below the maximum rated power (Maximum rated
power = Vo,set x Io,max).
Overcurrent Protection
To provide protection in a fault (output overload)
condition, the unit is equipped with internal
current-limiting circuitry and can endure current
limiting continuously. At the point of current-limit
inception, the unit enters hiccup mode. The unit
operates normally once the output current is brought
back into its specified range. The average output
current during hiccup is 10% IO, max.

Thermal Considerations
The power modules operate in a variety of thermal
environments; however, sufficient cooling should be
provided to help ensure reliable operation.
Considerations include ambient temperature, airflow,
module power dissipation, and the need for increased
reliability. A reduction in the operating temperature of
the module will result in an increase in reliability. The
thermal data presented here is based on physical
measurements taken in a wind tunnel as shown in the
Figure 13.

Heat Transfer via Convection
Increased airflow over the module enhances the heat
transfer via convection. Derating figures showing the
maximum output current that can be delivered by
each module versus local ambient temperature (TA)

Surface Mount Information
Pick and Place
The SMT versions of the EQW series of DC-to-DC
power converters use an open-frame construction and
are designed for surface mount assembly within a
fully automated manufacturing process.
damage to the modules, and can adversely affect
long-term reliability.
The surface mountable modules in the EQW family
use our newest SMT technology called “Column Pin”
(CP) connectors. Figure 17 shows the new CP
connector before and after reflow soldering onto the
end-board assembly.
The EQW-S series modules are fitted with a label
designed to provide a large flat surface for pick and
placing. The label is located covering the center of
gravity of the power module. The label meets all the
requirements for surface-mount processing, as well
as meeting UL safety agency standards. The label will
withstand reflow temperatures up to 300°C. The label
also carries product information such as product
code, date and location of manufacture.

Reflow Soldering.
The CP is constructed from a solid copper pin with an
integral solder ball attached, which is composed of
tin/lead (Sn/Pb-63/37) solder. The CP connector
design is able to compensate for large amounts of coplanarity and still ensure a reliable SMT solder joint.
Z Plane Height
The ‘Z’ plane height of the pick and place label is 9.15
mm (0.360 in) nominal with an RSS tolerance of +/0.25 mm.
Nozzle Recommendations
The module weight has been kept to a minimum by
using open frame construction. Even so, they have a
relatively large mass when compared with
conventional smt components. Variables such as
nozzle size, tip style, vacuum pressure and placement
speed should be considered to optimize this process.
The minimum recommended nozzle diameter for
reliable operation is 6mm. The maximum nozzle outer
diameter, which will safely fit within the allowable
component spacing, is 9 mm. Oblong or oval nozzles
up to 11 x 9 mm may also be used within the space
available.
For further information please contact your local
Lineage Power Technical Sales Representative.
Tin Lead Soldering
The following instructions must be observed when
SMT soldering these units. Failure to observe these
instructions may result in the failure of or cause

o
Typically, the eutectic solder melts at 183 C, wets the
land, and subsequently wicks the device connection.
Sufficient time must be allowed to fuse the plating on
the connection to ensure a reliable solder joint. There
are several types of SMT reflow technologies
currently used in the industry. These surface mount
power modules can be reliably soldered using natural
forced convection, IR (radiant infrared), or a
combination of convection/IR. For reliable soldering
the solder reflow profile should be established by
accurately measuring the modules CP connector
temperatures.

Post solder cleaning is usually the final circuit-board
assembly process prior to electrical board testing. The
result of inadequate cleaning and drying can affect
both the reliability of a power module and the
testability of the finished circuit-board assembly. For
guidance on appropriate soldering, cleaning and
drying procedures, refer to Lineage Power Board

The –Z version of the EQW006 modules are lead-free
(Pb-free) and RoHS compliant and are both forward
and backward compatible in a Pb-free and a SnPb
soldering process. Failure to observe the instructions
below may result in the failure of or cause damage to
the modules and can adversely affect long-term
reliability.

Pb-free Reflow Profile
Power Systems will comply with J-STD-020 Rev. C
(Moisture/Reflow Sensitivity Classification for
Nonhermetic Solid State Surface Mount Devices) for
both Pb-free solder profiles and MSL classification
procedures. This standard provides a recommended
forced-air-convection reflow profile based on the
volume and thickness of the package (table 4-2). The
suggested Pb-free solder paste is Sn/Ag/Cu (SAC).
The recommended linear reflow profile using
Sn/Ag/Cu solder is shown in Fig. 20.
MSL Rating
The EQW006 modules have a MSL rating of 2.
Storage and Handling
The recommended storage environment and handling
procedures for moisture-sensitive surface mount
packages is detailed in J-STD-033 Rev. A (Handling,
Packing, Shipping and Use of Moisture/Reflow
Sensitive Surface Mount Devices). Moisture barrier
bags (MBB) with desiccant are required for MSL
ratings of 2 or greater. These sealed packages
should not be broken until time of use. Once the
original package is broken, the floor life of the product
at conditions of ≤ 30°C and 60% relative humidity
varies according to the MSL rating (see J-STD-033A).

Through-Hole Lead-Free Soldering
Information
The RoHS-compliant through-hole products use the
SAC (Sn/Ag/Cu) Pb-free solder and RoHS-compliant
components. They are designed to be processed
through single or dual wave soldering machines. The
pins have an RoHS-compliant finish that is compatible
with both Pb and Pb-free wave soldering processes.
A maximum preheat rate of 3°C/s is suggested. The
wave preheat process should be such that the
temperature of the power module board is kept below
210°C. For Pb solder, the recommended pot
temperature is 260°C, while the Pb-free solder pot is
270°C max. Not all RoHS-compliant through-hole
products can be processed with paste-through-hole
Pb or Pb-free reflow process. If additional information
is needed, please consult with your Lineage Power
representative for more details.
