Overview

Quarter-Brick Series Dual output DC/DC CONVERTERS • • • • • • • • • • High Current, High Efficiency, Low Profile NEW Product 1 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.

Key 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 international safety agency approvals, including EN60950-1 and UL/cUL60950, this series reduces compliance cos.
