Preliminary Product Brief * For Discussion with Tyco Electronics Customers Only - Tyco Electronics Proprietary QW 15A single output series Industry standard Quarter brick DC/DC converter, 36Vdc-75Vdc (48V) input voltage range, Output voltages available from 5V-1.0Vdc I II * Delivers up to 20A output current * Ultra High Efficiency: 91% @ 3.3V full load * Low output voltages down to 1V: supports migration to future IC and microprocessor supply voltages * Through hole and SMT * Cost efficient open frame design * Low profile 8.5mm (0.33") IV (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.
