Description
The QBVW025A0B Barracuda series of dc-dc converters are a new generation of fully regulated DC/DC power modules designed
to support 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 QBVW025A0B series operate from
an input voltage range of 36 to 75Vdc and provide up to 25A output current at output voltages of 12Vdc 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 96% at 12V 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.
