LQD40A48-3V3-1V5EY

Quarter-Brick Series Dual output DC/DC CONVERTERS High Current, High Efficiency, Low Profile 1 NEW Product • • • • • • • • • • Two independent outputs High full load efficiency 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 efficiency, open-frame, isolated 40 A converters in an industry standard dual quarter-brick footprint. These converters deliver high output current at low voltages, and excellent useable power density for today’s high end applications. This series features an input voltage 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 efficiencies are 90%. This series also has a remote ON/OFF capability. 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 reduces compliance costs and time to market.
