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.

SCOPE
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. 60950-1rd
03 and VDE 0805 (IEC60950, 3 Ed).
These converters have been evaluated to the spacing
requirements for Basic Insulation, per the above
safety standards; and 1500Vdc is applied from Vin to
Vout to 100% of outgoing production..
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
(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.

Design Considerations
The power module has ELV (extra-low voltage)
outputs when all inputs are ELV.
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
33μF electrolytic capacitor (ESR<0.7Ω at 100kHz),
mounted close to the power module helps ensure the
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.

36 - 75Vdc Input; 1.2Vdc to 5Vdc Output; 12A to 25A Output
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.
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 (Figure 40). Logic low
is –0.7V ≤ Von/off ≤ 1.2V. The maximum Ion/off during
a logic low is 1mA, the switch should be maintain a
logic low level while sinking this current.
During a logic high, the typical Von/off generated by the
module is 15V, and the maximum allowable leakage
current at Von/off = 15V is 10μA.
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(-).
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).

Connecting an external resistor (Rtrim-down) between

be ±0.1%.
The following equation determines the required
external resistor value to obtain a percentage output
voltage change of Δ%
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 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

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.

Location.
Please refer to the Application Note “Thermal
Characterization Process For Open-Frame BoardMounted Power Modules” for a detailed discussion of
thermal aspects including maximum device
temperatures.
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)
for natural convection and up to 2m/s (400 ft./min) are
shown in the respective Characteristics Curves
section.
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
o
Tref (Figure 43), exceeds 125 C (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.
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.

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.

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.
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.

Solder Ball
End assembly PCB
Figure 48. Column Pin Connector Before and After
Reflow Soldering .
The CP is constructed from a solid copper pin with an
integral solder ball attached, which is composed of
tin/lead (Sn63/Pb37) solder for non-Z codes, or
Sn/Ag3.8/Cu0.7 (SAC) solder for –Z codes. The CP
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 183oC (Sn/Pb solder) or 217-218 oC (SAC solder),
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.
Nozzle Recommendations
The module weight has been kept to a minimum by
using open frame construction. Even so, they have a

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
