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 technol-
ogy 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.
