Quarter-Brick Series D u a l ou t p u t DC/DC CONVERTERS High Current, High Eciency, Low Prole 1 NEW Product • Two independent outputs • High full load eciency • Wide ambient temperature range of -40 ºC to +85 ºC • Up to 100% load imbalance • Tracking, monotonic start-up • Starts into pre-biased outputs • Basic insulation system • Over-voltage and over-temperature protection • 100 V, 100 ms input voltage transient response • Secondary side control, no optocouplers, fast transient load response • Available RoHS compliant These are new high eciency, open-frame, isolated 40 A converters in an industry standard dual quarter-brick footprint. These converters deliver high output current at low voltages, and excel- lent useable power density for today’s high end applications. This series features an input volt- age range of 36 Vdc to 75 Vdc and output voltages of 1.2 V/3.3 V, 1.5 V/3.3 V, 1.8 V/3.3 V 2.5 V/3.3 V, and 5 V/3.3 V. The output voltage on each model is adjustable from 90% to 110% of the nominal value. Typical eciencies are 90%. This series also has a remote ON/OFF capabili- ty. Over-current and over-voltage protection features are included as standard. Designed to meet inter national safety agency approvals, including EN60950-1 and UL/cUL60950, this series 2 YEAR WARRANTY reduces compliance costs and time to market.
