LQS Series 54–100 Watt Quarter-Brick Isolated DC-DC Converters (48 V Input Models)
The LQS series of quarter-brick isolated DC-DC converters includes 14 models with a wide 2:1 input range of 36 to 75Vdc, designed primarily for use with standard 48 V telecommunications equipment supplies. Offering single output voltages of 1.2 V, 1.5 V, 1.8 V, 3.3 V or 5 V, these converters are available in three different performance categories for maximum applications flexibility. The series includes models with up to 100 amps output capability.
LQS series converters accommodate a wide ambient operating temperature range of -40 to 85˚C and offer efficiencies as high as 92%. All the converters are based on an open-frame design that is optimized for forced air cooling,
Standard features include output trim, remote enable and differential remote sense, with non-latching overvoltage and overtemperature protection, as well as continuous protection against short circuits. The LQS series converters have an installed height of just 0.3 inch (7.6 mm), making them ideal for systems with demanding inter-board spacing requirements.
