Quarter-Brick Series Dual output DC/DC CONVERTERS High Current, High Efficiency, Low Profile • Two independent outputs • High full load efficiency • Wide ambient temperature range of -40ºC to +85ºC • Up to 100% load imbalance • Tracking, monotonic start-up • Starts into pre-biased outputs • Basic insulation system • Over-voltage and over-temperature protection • 100V, 100ms input voltage transient response • Secondary side control, no optocouplers, fast transient load response These are new high efficiency, open-frame, isolated 40A 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 to 75VDC and output voltages of 1.2V/3.3V, 1.5V/3.3V, 1.8V/3.3V 2.5V/3.3V, and 5.0V/3.3V. The output voltage on each model is adjustable from 90% to 110% of the nominal value. Typical efficiencies are This series also has a remote ON/OFF capability. Over-current and over-voltage protection features are included as standard. Designed to meet international safety agency approvals, including EN60950 and UL/cUL60950, this series reduces compliance costs and time to market.
