Description
The QBVW033A0B 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 QBVW033A0B series operate from an
input voltage range of 36 to 75Vdc and provide up to 33A output current at output voltages of 12V in an industry standard,
dc
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.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings
only, functional operation of the device is not implied at these or any other conditions in excess of those given in the operations
sections of the Data Sheet. Exposure to absolute maximum ratings for extended periods can adversely affect device reliability.

CAUTION: This power module is not internally fused. An input line fuse must always be used.
This power module can be used in a wide variety of applications, ranging from simple standalone operation to an integrated part
of sophisticated power architecture. To preserve maximum flexibility, internal fusing is not included, however, to achieve maximum
safety and system protection, always use an input line fuse. The safety agencies require a fast-acting fuse with a maximum rating
of 30 A in the ungrounded input lead of the power supply (see Safety Considerations section). Based on the information provided in
this Data Sheet on inrush energy and maximum dc input current, the same type of fuse with a lower rating can be used. Refer to
the fuse manufacturers Data Sheet for further information.
