Description
The QPW-series dc-dc converters are a new generation of DC/DC power modules designed for maximum efficiency
and power density. The QPW series provide up to 60A output current in an industry standard quarter brick. The
converter incorporates synchronous rectification technology and innovative packaging techniques to achieve ultra
high efficiency reaching 93% at 3.3V 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 QPW series power modules are isolated
dc-dc converters that operate over a wide input voltage range of 36 to 75 Vdc and provide single precisely regulated
output. The output is fully isolated from the input, allowing versatile polarity configurations and grounding
connections.
