Description
The QUK-series dc-dc converters are a new generation of DC/DC power modules designed to support intermediate
bus applications where multiple low voltages are generated using discrete/modular point of load (POL) converters.
The QUK series provide up to 240 watts of output power in an industry standard quarter brick, which makes it an
ideal choice for dense, high current and intermediate bus voltage applications. The converter incorporates
synchronous rectification technology and innovative packaging techniques to achieve ultra high efficiency reaching
95.5% at 9.0V full load. The ultra high efficiency of this converter leads to lower power dissipation such that for most
applications a heat sink is not required. The QUK series power modules are isolated dc-dc converters that operate
over an intermediate input voltage range of 36 to 55 Vdc and provide a single unregulated output voltage with a 5:1
step-down ratio between input and 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.
