Low-cost converters

Powercube's LPD150 series dc-to-dc converters employ an innovative topology similar to a standard forward converter with special integrated magnetics to reduce component count over competing converter designs. The converters provide advanced features such as thermal shutdown and over-voltage protection as standard offerings. They offer input, output, and baseplate isolation of more than 2500 VRMS and efficiencies as high as 90%. All models operate at a frequency of 375 kHz and are available with input voltages of 12, 24, 48, 72, 150, or 300 V. LPD150 models, including those offering 300-V input, meet their specs to temperatures of 100ºC.
