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.
