Description
The QBDW033A0B Barracuda series of dc-dc converters are a new generation of DC/DC power modules designed to support 9.6
-12V
dc
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 QBDW033A0B series operate from an
input voltage range of 36 to 75V
dc
and provide up to 33A output current at output voltages from 8.1V
dc
to 12V
dc
, and 400W
output power from output voltages of 12.1V
dc
to 13.2V
dc
in a DOSA standard quarter brick. The converter incorporates digital
control, synchronous rectification technology, a fully regulated control topology, and innovative packaging techniques to achieve
efficiency exceeding 96% peak at 12V
dc
output. This leads to lower power dissipations such that for many applications a heat
sink is not required. Standard features include output voltage trim, remote sense, on/off control, output overcurrent and over
voltage protection, over temperature protection, input under and over voltage lockout, power good signal and PMBus interface.
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.
