Description
The QBVE060A0S10R4 Barracuda series of dc-dc converters are a new generation of fully regulated DC/DC power modules
designed to support 10.4Vdc 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 QBVE060A0S10R4 series
operate from an input voltage range of 45 to 56Vdc and provide up to 60.0A output current at output voltages of 10.4V
dc
in an
industry standard, DOSA compliant quarter brick. The converter incorporates digital control, synchronous rectification technology,
a fully regulated control topology, and innovative packaging techniques to achieve efficiency exceeding 97% at 10.4V 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.
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
QBVE060A0S10R4 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 30A in the ungrounded input lead of the power supply (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.
