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, which makes it an ideal choice for small space, high current and low voltage
applications. 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
