Description
The QBVE078A0S10R4 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 QBVE078A0S10R4 series
operate from an input voltage range of 45 to 56Vdc and provide up to 78.0A output current at output voltages of 10.4Vdc 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.
