Description
The QBVK037A5S9R6 Barracuda series of dc-dc converters are a new generation of fully regulated DC/DC power modules
designed to support 9.6Vdc 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 QBVK037A5S9R6 series operate
from an input voltage range of 38 to 55Vdc and provide up to 37.5A output current at output voltages of 9.6Vdc 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 95.8% at 9.6V 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.
