Description
The QBVW033A0B series of dc-dc converters are a new generation of 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 QBVW033A0B series
operate from an input voltage range of 36 to 75Vdc and provide up to 33A output current at output voltages of 12V
dc
in an industry 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% 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.
