Description  
The QBK025A0B series of DC-DC converters are an expansion of a new generation of DC/DC power modules  
designed to support 12Vdc intermediate bus applications where multiple low voltages are subsequently generated  
using discrete/modular point of load (POL) converters. The QBK025A0B series provide up to 25A output current in  
an industry standard quarter brick, which makes it an ideal choice for small space, high current and 12V  
intermediate bus voltage applications. The converter incorporates synchronous rectification technology and  
innovative packaging techniques to achieve efficiency reaching 94% at 12V full load. This leads to lower power  
dissipations such that for many applications a heat sink is not required. 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.
