Texas Instruments has launched a single-chip power management integrated circuit that promises to reduce the amount of power consumed in multi-kilowatt servers, communications equipment and industrial systems by at least 25%.
The new UCC28070 two-phase, average current-mode controller was designed to simplify power design and achieve a greater than 0.9 power factor rating, said the company.
The device also enables designers to exceed energy guidelines set forth by The Green Grid, Climate Savers Computing Initiative and Project Big Green.
It also promises to help boost system reliability with what TI claims is a unique 180 degree interleaving method, which reduces the amount of input and output current ripple and distributes the magnetics to improve thermal management. TI said the upshot is between 50% and 100% reduction in ripple compared to typical non-interleaved PFC architectures.
