As tablets and other mobile devices boost processing speeds, they require power supplies for low voltages and large current drives. They also require multi-application power supplies, and must also reduce noise to compensate for downsizing of PCBs.

Toshiba’s new multi-output system power IC offers a high efficiency, large current drive with 2-ch DC-DC converters, 4-ch serialized regulators for noise reduction, and 1-ch load switch. Each DC-DC converter drives with a different oscillation frequency, reducing the switching noise peak. The ability to change output voltage and the rising sequence through the I2C bus ensures the IC can support diverse applications.
