QW 15A single output series
(approval pending)
The QW-series dc-dc converters are a new generation
of DC/DC power modules designed for optimum
efficiency. The QW provides up to 15A output current
in an industry standard quarter brick, which makes it
an ideal choice for small space and low voltage
applications. The converter uses synchronous
rectification technology and innovative packaging
techniques to achieve ultra high efficiency reaching
92% 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 QW-series supports future
migration of semiconductor and microprocessor supply
voltages down to 1.0V.
