 LQS50A48-3V3AJ
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 -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 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 efficiencies 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 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
