Description

The QBDW025A0B Barracuda series of dc-dc converters are a new generation of DC/DC power modules designed to support 9.6

-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 QBDW025A0B series operate from an

input voltage range of 36 to 75Vdc and provide up to 25A output current at output voltages from 8.1V_dcto 12V_dcin 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 approaching 96% peak at 12V_dcoutput. 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.
