DC/DC CONVERTERS
High Current, High Efficiency, Low Profile
NEW Product
1
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 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 costs and time to market.
All specifications are typical at nominal input, full load at 25°C ambient unless otherwise stated
