2014 IEEE International Solid-State Circuits Conference
(BUSINESS WIRE)-- Toshiba Corporation (TOKYO:6502) today announced that it has developed a new DC-DC converter for mobile devices that offers over 85% efficiency across a load current range more than 3 times wider than that of typical DC-DC converters. Largely due to a new fast and low-ripple phase adding/dropping scheme, the converter eliminates more than 58% of power dissipation during a light load condition, and more than 24% during a heavy load condition.
Toshiba presented this development at the 2014 IEEE International Solid-State Circuits Conference in San Francisco, California, on February 10.
Today’s processors utilize multicore designs, resulting in a wide range of current profiles, and require DC-DC converters with a good efficiency over a wide range of load currents. This is realized by using a multiphase architecture that delivers current from
