Description
The QRW-series dc-dc converters are a new generation of DC/DC power modules designed for optimum efficiency
and power density. The QRW series provide 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.
