Preliminary Product Brief * For Discussion with Tyco Electronics Customers Only - Tyco Electronics Proprietary JRW 70A single output series Industry standard Half brick DC/DC converter, 36Vdc-75Vdc (48V) input voltage range, Output voltages available from 12V down to 1.0V I II III * Delivers up to 70A output current * Ultra High Efficiency: 91% @ 3.3V full load * Optimal Thermal Performance * High power density: 96 W/in * Low output voltages down to 1V: supports migration to future IC and microprocessor supply voltages * Active load sharing option: Parallel operation * Cost efficient open frame design IV (approval pending) The JRW-series dc-dc converters are a new generation of DC/DC power modules designed for optimum efficiency and power density. The JRW provides up to 70A output current in an industry standard half 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. The ultra high efficiency of this converter results in low power dissipation, such that for most applications a heat sink is not required. In addition, the JRW-series supports future migration of semiconductor and microprocessor supply voltages down to 1.0V.
