Toshiba New General Purpose Multi-Output System Power IC Realizes Large Current and Lower Noise Drive

2016-12-01 | Return

TOKYO–Toshiba Corporation's (TOKYO: 6502) Storage & Electronic Devices Solutions Company today launched "TC7739FTG,” a general purpose, multi-output system power IC equipped with DC-DC power supplies and serialized regulators. Mass production will start at the end of this month.

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.

Applications

Information devices such as smartphones and tablets

Main Features

。Step-down DCDC converters (2 ch) + LDO (4 ch) + Load SW (1 ch)
