Description

The QBVW025A0B 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 12V_dcin 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.
