Description
The EBVW020A0B series of dc-dc converters are a new generation of DC/DC power modules designed to support 9.6 -12V
dc
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 EBVW020A0B series operate from an input voltage
range of 36 to 75V
dc
, and provide up to 20A output current
at output voltages from 6.0V
dc
to 12.0V
dc
, and 240W output power
from output voltages of 12.1V
dc
to 13.2V
dc
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 12V
dc
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 6.0V
dc
to 13.2V
dc
, 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.

Absolute Maximum Ratings
Data Sheet
EBVW020A0B Barracuda Series; DC-DC Converter Power Modules
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings
only, functional operation of the device is not implied at these or any other conditions in excess of those given in the operations
sections of the Data Sheet. Exposure to absolute maximum ratings for extended periods can adversely affect device reliability.

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.
