Description
The EUE-series 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 EUE series
provide up to 200 watt output power in an industry standard Eighth brick, which makes it an ideal choice for compact
space, high current and intermediate bus voltage applications. The converter incorporates synchronous rectification
technology and innovative packaging techniques to achieve ultra high efficiency reaching 95.3% at 11.6V 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 EUE series power modules are isolated DC-DC converters that provide a single unregulated
output voltage with a 4:1 step-down ratio between input/output.
