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 international safety agency approvals, including EN60950-1 and UL/cUL60950, this series
reduces compliance costs and time to market.

The part number cannot exceed 18 characters. If the desired part
number with options contains 19 characters then the last dash ‘-’ in the
part number is removed i.e. LQD25A48-5V0-3V3RAJ becomes
LQD25A48-5V03V3RAJ. If the desired part number with options contains
20 characters then all dashes ‘-’ are removed, i.e. LQD25A48-5V03V3RANJ becomes LQD25A485V03V3RANJ.
