Description
The QBVS050A0B Barracuda series of dc-dc converters are a new generation of fully regulated DC/DC power modules designed to
support 12.0Vdc 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 QBVS050A0B series operate from an input
voltage range of 52 to 60Vdc and provide up to 50.0A output current at output voltages of 12.0Vdc 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 12.0V 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.
