Converters Feature High, Flat Efficiency Curves

A range of quarter-brick 100-W to 200-W isolated dc-dc converters, the iQE series designed by TDK Innoveta, is available from Lambda. Typical efficiency of the series is 90% over a wide load range of 20% to 100% of the maximum rated current (flat for 80% of the power curve). With a range of output voltages from 3.3 Vdc to 15 Vdc, the series includes models that operate from a nominal 24-Vdc or 48-Vdc input.

The single-output iQE series is offered with two input-voltage ranges, 18 Vdc to 36 Vdc, or 36 Vdc to 75 Vdc. Available output voltages are 3.3 Vdc, 5 Vdc, 8 Vdc, 12 Vdc or 15 Vdc, each with a user-adjustment range of ±10%. The iQE series converters are approved to international safety standards including UL, CSA, EN, CE, IEC and VDE. The series is available now with prices starting at $51.50 each in 100-piece quantities.
