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. RoHS Compliant |
