Description

The QBW018A0B 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 QBW018A0B series provide up to 18A 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 ultra high efficiency reaching 93% at 12V full load. This leads to lower

power dissipation such that for many applications a heat sink is not required.

The QBW018A0B series power modules are isolated dc-dc converters that operate over an input voltage range from

36 to 75 Vdc and provide a single regulated output. 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.
