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 12Vdc in 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.

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
manufacturer’s Data Sheet for further information.

(Moisture/Reflow Sensitivity Classification for
Nonhermetic Solid State Surface Mount Devices) for both Pbfree solder profiles and MSL classification
procedures. BMP will comply with JEDEC J-STD-020C
specification for 3 times reflow requirement. The suggested
Pb-free solder paste is Sn/Ag/Cu (SAC). The recommended
linear reflow profile using Sn/Ag/Cu solder is shown in Figure
24.

MSL Rating
The QBVW033A0B modules have a MSL rating as indicated in
the Device Codes table, last page of this document.
Storage and Handling
The recommended storage environment and handling
procedures for moisture-sensitive surface mount packages is
detailed in J-STD-033 Rev. A (Handling, Packing, Shipping and
Use of Moisture/Reflow Sensitive Surface Mount Devices).
Moisture barrier bags (MBB) with desiccant are required for
MSL ratings of 2 or greater. These sealed packages should not
be broken until time of use. Once the original package is
broken, the floor life of the product at conditions of 30°C and
60% relative humidity varies according to the MSL rating (see
J-STD-033A). The shelf life for dry packed SMT packages will
be a minimum of 12 months from the bag seal date, when
stored at the following conditions: < 40° C, < 90% relative
humidity.
Post Solder Cleaning and Drying
Considerations
Post solder cleaning is usually the final circuit-board assembly
process prior to electrical board testing. The result of
inadequate cleaning and drying can affect both the reliability
of a power module and the testability of the finished
circuit-board assembly. For guidance on appropriate
soldering, cleaning and drying procedures, refer to GE Board
Mounted Power Modules: Soldering and Cleaning Application
Note (AN04-001).
