Description
The EBVW025A0B BARRACUDA series of dc-dc converters are a new generation of DC/DC power modules designed to support 9.6
-12Vdc intermediate bus applications where multiple low voltages are subsequently generated using point of load (POL) converters,
as well as other application requiring a tightly regulated output voltage. The EBVW025A0B series operate from an input voltage
range of 36 to 75Vdc, and provide up to 25A output current at output voltages from 6.0Vdc to 12.0Vdc, and 300W output power from
output voltages of 12.1Vdc to 13.2Vdc in a DOSA standard eighth brick. The converter incorporates digital control, synchronous
rectification technology, and innovative packaging techniques to achieve efficiency reaching 95.4% peak at 12Vdc output. This
leads to lower power dissipations such that for many applications a heat sink is not required. Standard features include on/off
control, output overcurrent and over voltage protection, over temperature protection, input under and over voltage lockout.
Optional features include output voltage remote sense and trim from 6.0Vdc to 13.2Vdc, passive droop paralleling, and base plate
for heat sink or cold wall applications.
The output is fully isolated from the input, allowing versatile polarity configurations and grounding connections. Built-in filtering for
both input and output minimizes the need for external filtering.

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 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 15 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.

(Moisture/Reflow Sensitivity Classification for

procedures. BMP will comply with JEDEC J-STD-020C
specification for 3 times reflow requirement. The suggested
Pb-free solder paste is Sn/Ag/Cu (SAC). The recommended
linear reflow profile using Sn/Ag/Cu solder is shown in Figure
23.
Layout Considerations
Temp
Peak Temp. 240 -245°C
The EBVW025 power module series are low profile in order to
be used in fine pitch system card architectures. As such,
component clearance between the bottom of the power
module and the mounting board is limited. Avoid placing
copper areas on the outer layer directly underneath the power
module. Also avoid placing via interconnects underneath the
power module.

Through-Hole Lead-Free Soldering
Information
The RoHS-compliant, Z version, through-hole products use the
SAC (Sn/Ag/Cu) Pb-free solder and RoHS-compliant
components. The non-Z version products use lead-tin (Pb/Sn)
solder and RoHS-compliant components. Both version
modules are designed to be processed through single or dual
wave soldering machines. The pins have an RoHS-compliant,
pure tin finish that is compatible with both Pb and Pb-free
wave soldering processes. A maximum preheat rate of 3C/s is

Data Sheet
EBVW025A0B Barracuda Series; DC-DC Converter Power Modules
36-75Vdc Input; 12.0Vdc, 25.0A, 300W Output
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-025A). 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 GE Board Mounted
Power Modules: Soldering and Cleaning Application Note
(AP01-056EPS).
EMC Considerations
The circuit and plots in Figure 24 shows a suggested
configuration to meet the conducted emission limits of
Level
EN55022 Class B. For further information on designing for EMC
compliance, please refer to the FLT007A0 data sheet.
