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.
