Description
The ESTW006A0B [Barracuda™] Series, eighth-brick, low-height power modules are isolated DC-DC converters
that provide a single, precisely regulated output voltage over an input voltage range of 36-75V
provides 12V
nominal output voltage rated for 6Adc output current. The module incorporates Lineage Power’s vast
dc
heritage for reliability and quality, while also using the latest in technology and component and process
standardization to achieve highly competitive cost. The open frame module construction, available in both surface
mount and through-hole packaging, enables designers to develop cost and space efficient solutions. The module
achieves typical full load efficiency greater than 90% at V
=48Vdc. Standard features include remote On/Off, remote
IN
sense, output voltage adjustment, overvoltage, overcurrent and overtemperature protection. An optional heat plate
allows for external standard, eighth-brick heat sink attachment to achieve higher output current in high temperature
applications.

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 fast-acting fuse with a maximum rating of 10 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.

Design Considerations
Input Filtering
The power module should be connected to a low AC
impedance source. Highly inductive source
impedance can affect the stability of the power
module. For the test configuration in Figure 7, a 33100μF electrolytic capacitor (ESR<0.7 at 100kHz),
mounting close to the power module helps ensure the
stability of the unit. Consult the factory for further
application guidelines.
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.60950-1,
and VDE0805-1(IEC60950-1).
If the input source is non-SELV (ELV or a hazardous
voltage greater than 60 Vdc and less than or equal to
75Vdc), for the module’s output to be considered as
meeting the requirements for safety extra-low voltage
(SELV), all of the following must be true:
The input source is to be provided with reinforced
insulation from any other hazardous voltages,
including the AC mains.
One V
pin and one V
IN
pin are to be
OUT
grounded, or both the input and output pins are
to be kept floating.
The input pins of the module are not operator
accessible.
Another SELV reliability test is conducted on the
whole system (combination of supply source and
subject module) as required by the safety
agencies to verify that under a single fault,
hazardous voltages do not appear at the
module’s output.
Note: Do not ground either of the input pins of the
module without grounding one of the output
pins. This may allow a non-SELV voltage to
appear between the output pins and ground.
The power module has extra-low voltage (ELV)
outputs when all inputs are ELV.
All flammable materials used in the manufacturing of
these modules are rated 94V-0 or tested to the
UL60950 A.2 for reduced thickness.
For input voltages exceeding –60 Vdc but less than or
equal to –75 Vdc, these converters have been
evaluated to the applicable requirements of basic
insulation between secondary DC mains distribution
input (classified as TNV-2 in Europe) and unearthed
SELV outputs.
The input to these units is to be provided with a
maximum 10 A fast-acting fuse in the ungrounded
lead.

Feature Descriptions
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.
36 - 75Vdc Input; 12V/6A
Output
dc
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).

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 V

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:
[V
(+) – VO(–)] – [SENSE(+) – SENSE(–)] 0.5 V
O
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.

Input Undervoltage Lockout
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, V
UV/ON
.
Once operating, the module will continue to operate
until the input voltage is taken below the undervoltage
turn-off threshold, V
UV/OFF
.
Overtemperature Protection
To provide protection under certain fault conditions,
the unit is equipped with a thermal shutdown circuit.
The unit will shut down if the thermal reference point,
Tref, exceeds 135
O
C (Figure 13, typical) or 120 OC
(Figure 14, typical), but the thermal shutdown is not
intended as a guarantee that the unit will survive
temperatures beyond its rating. The module will
automatically restart upon cool-down to a safe
temperature.
Output Overvoltage Protection
The output overvoltage protection scheme of the
modules has an independent overvoltage loop to
prevent single point of failure. This protection feature
latches in the event of overvoltage across the output.
Cycling the On/Off pin or input voltage resets the
latching protection feature. If the auto-restart option
(4) is ordered, the module will automatically restart
upon an internally programmed time elapsing.
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. If the unit is
not configured with auto–restart, it will latch off
following the overcurrent condition. The module can
be restarted by cycling the DC input power for at least
LINEAGEPOWER7
Page 8

November 5, 2012
ESTW006A0B Series Eighth-Brick Power Modules
one second or by toggling the remote On/Off signal
for at least one second.
If the unit is configured with the auto-restart option (4),
it will remain in the hiccup mode as long as the
overcurrent condition exists. Once the output current
is brought back into its specified range, the unit will
operate normally. The average output current during
hiccup is 10% I
O, max
.
Output Voltage Programming
Trimming allows the output voltage set point to be
increased or decreased from the default value. This is
accomplished by connecting an external resistor

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 = V
O,set
x I
O,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.
The thermal reference points, T

Lead-Free Soldering
The ESTW006A0Bxx RoHS-compliant through-hole
products use 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 a RoHS-compliant finish
that is compatible with both Pb and Pb-free wave
soldering processes. A maximum preheat rate of
3C/s is suggested. The wave preheat process
should be such that the temperature of the power
module board is kept below 210C. For Pb solder,
the recommended pot temperature is 260C, while the
Pb-free solder pot is 270C max.
Paste-in-Hole Soldering
The ESTW006A0Bxx module is compatible with
reflow paste-in-hole soldering processes shown in
Figures 23-25. Since the ESTW006A0BxxZ module is
not packaged per J-STD-033 Rev.A, the module must
be baked prior to the paste-in-hole reflow process.
ESTW006A0Bxx-HZ modules are not compatible with
paste-in-hole reflow soldering. Please contact your
Lineage Power Sales Representative for further
information.

ESTW006A0B Series Eighth-Brick Power Modules
Surface Mount Information
MSL Rating
The ESTW006A0B-SZ module has 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 provided for the
ESTW006A0Bxx-SZ modules. 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
humidity varies according to the MSL rating (see JSTD-033A). The shelf life for dry packed SMT
packages is a minimum of 12 months from the bag
seal date, when stored at the following conditions: <
40° C, < 90% relative humidity
Pick and Place
The ESTW006A0Bxx-S modules use an open frame
construction and are designed for a fully automated
assembly process. The modules are fitted with a
label designed to provide a large surface area for pick
and place operations. The label meets all the
requirements for surface mount processing, as well as
safety standards, and is able to withstand reflow
temperatures of up to 300
product information such as product code, serial
number and the location of manufacture.
Figure 21. Pick and Place Location.
Nozzle Recommendations
The module weight has been kept to a minimum by
using open frame construction. Even so, these
modules have a relatively large mass when compared
to 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.

technology called “Column Pin” (CP) connectors.
Figure 22 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/Pb) solder for non-Z codes, or Sn/Ag
(SAC) solder for –Z codes.

The CP connector design is able to compensate for
large amounts of planarity and still ensure a reliable
SMT solder joint. Typically, the eutectic solder melts
at 363°C (Sn/Pb solder) or 217-236°C (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.
Tin Lead Soldering
The ESTW006A0Bxx-S power modules are lead free
modules and can be soldered either in a lead-free
solder process or in a conventional Tin/Lead (Sn/Pb)
process. It is recommended that the customer review
data sheets in order to customize the solder reflow
profile for each application board assembly. The
following instructions must be observed when
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.
In a conventional Tin/Lead (Sn/Pb) solder process,
peak reflow temperatures are limited to less than
235°C. Typically, the eutectic solder melts at 363°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

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 Mounted Power Modules: Soldering and Cleanin g
