(approval pending)
• Delivers up to 40A output current
• Ultra High Efficiency: 91% @ 3.3V full load
• Improved Thermal Performance:
25A at 70°C at 1ms^-1 (200LFM)
• High power density: 100W/in³
• Low output voltages down to 1V:
supports migration to future IC and
microprocessor supply voltages
• Active load sharing option: Paralleling
• Cost efficient open frame design
• Optional heat-sink: to permit operation
over extended ambient temperature ranges
The QRW-series dc-dc converters are a new
generation of DC/DC power modules designed for
optimum efficiency and power density. The QRW
provides up to 40A 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 uses synchronous
rectification technology and innovative packaging
techniques to achieve ultra high efficiency reaching
91% at 3.3V full load. Thanks to the ultra high
efficiency of this converter, the power dissipation is
such that for most applications a heat sink is not
required. In addition, the QRW-series supports future
migration of semiconductor and microprocessor supply
voltages down to 1.0V.
