Description

The EQW series, Eighth-brick power modules are isolated dc-dc converters that can deliver up to 25A of output
current and provide a precisely regulated output voltage over a wide range of input voltages (Vi = 36 -75Vdc). The
modules achieve full load efficiency of 88% at 3.3V 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, overvoltage, overcurrent and
overtemperature 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 a sophisticated power architecture. 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 fast-acting fuse with a maximum rating of 6A (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., UL60950-1, CSA C22.2 No. 60950-1­03 and VDE 0805 (IEC60950, 3

requirements for Basic Insulation, per the above
safety standards; and 1500Vdc is applied from V

out

For end products connected to –48V dc, or –60Vdc
nominal DC MAINS (i.e. central office dc battery
plant), no further fault testing is required. *Note: -60V
dc nominal battery plants are not available in the U.S.
or Canada.

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

Design Considerations

The power module should be connected to a low
ac-impedance source. A highly inductive source
impedance can affect the stability of the power
module. For the test configuration in Figure 37, a

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

.

33μF electrolytic capacitor (ESR<0.7 at 100kHz),
mounted close to the power module helps ensure the
stability of the unit. Consult the factory for further
application guidelines.

Remote Sense

Remote sense minimizes the effects of distribution
losses by regulating the voltage at the remote-sense
connections (See Figure 41). The voltage between
the remote-sense pins and the output terminals must
not exceed the output voltage sense range given in

An alternative set of trimming equations is available
as an option for 1.0V and 1.2V output modules, by
ordering the –V option. These equations will reduce
the resistance of the external programming resistor,

The value of the external trim resistor for the optional

the standard trim equations.

At 48Vin (+/- 2.5V), EQW series modules can be trim
down to 20% over the entire temperature range. This
allows for margining the unit during manufacturing
process if the set point voltage is lower than the
standard output voltage. Please consult your local
Lineage Power field application engineer for
additional details.

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).

Feature Description (Continued)

Overcurrent Protection

To provide protection in a fault (output overload)
condi¬tion, the module is equipped with internal
current-limiting circuitry, and can endure current
limiting continuously. At the instance of current-limit
inception, the output current begins to tail-out. When
an overcurrent condition exists beyond a few
seconds, the module enters a “hiccup” mode of
opera¬tion, whereby it shuts down and automatically
attempts to restart upon cooling. While the fault
condition exists, the module will remain in this hiccup
mode, and can remain in this mode until the fault is
cleared. The unit operates normally once the output
current is reduced back into its specified range.

Output Over Voltage Protection

The output overvoltage protection clamp consists of
control circuitry, independent of the primary regulation
loop, that monitors the voltage on the output
terminals. This control loop has a higher voltage set
point than the primary loop (See the overvoltage
clamp values in the Feature Specifications Table). In
a fault condition, the overvoltage clamp ensures that
the output voltage does not exceed Vo,ovsd, max.
This provides a redundant voltage-control that
reduces the risk of output overvoltage.

Input Undervoltage Lockout

At input voltages below the input undervoltage lockout
limit, the module operation is disabled. The module
will begin to operate at an input voltage between the
undervoltage lockout limit and the minimum operating
input voltage.

Overtemper a t u r e P r o t ection

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 43), exceeds 125
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.

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.

The thermal reference point, T
specifications is shown in Figure 43. For reliable

Through-Hole 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.

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.

The EQW-S series modules are fitted with a Kapton
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.

Figure 47. Pick and Place Location.

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.

Reflow Soldering Information

The surface mountable modules in the EQW family
use our newest SMT technology called “Column Pin”
(CP) connectors. Figure 48 shows the new CP
connector before and after reflow soldering onto the
end-board assembly.

The CP is constructed from a solid copper pin with an
integral solder ball attached, which is composed of
tin/lead (Sn
Sn/Ag
connector design is able to compensate for large
amounts of co-planarity and still ensure a reliable
SMT solder joint. Typically, the eutectic solder melts
at 183
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.

The following instructions must be observed when
SMT soldering these units. Failure to observe these
instructions may result in the failure of or cause
damage to the modules, and can adversely affect
long-term reliability.

Lead Free Soldering

The –Z version SMT modules of EQW series are
lead-free (Pb-free) and RoHS compliant and are
compatible in a Pb-free 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. D
(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. 51.

Figure 51. Recommended linear reflow profile
using Sn/Ag/Cu solder.

MSL Rating

The EQW series SMT modules have a MSL rating of
2a.

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).
The shelf life for dry packed SMT packages will be a
minimum of 12 months from the bag seal date, when
stored at the following conditions: < 40° C, < 90%
relative humidity.

Post Solder Cleaning and Drying
Considerations

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
