TOKYO -- April 24, 2013

Toshiba Corporation (TOKYO: 6502) today announced that it has launched a
sub-power management IC embedded with a DCDC step-down convertor and LDO (Low
Drop Out) for use in mobile products such as cellular phones and smartphones
that realizes high efficiency at a light load.

The new product "TC7732FTG", increases the coil drive frequency from the
widely used 2MHz to 4MHz, making it possible to use a smaller packaged 1.0μH
coil that takes up less space.

Output voltage can also be set by the I2C bus, securing a reduction of
circuits using resistor ICs. External IC parts can be reduced by integrating
other peripheral MOSFET and capacitors into the new product. These
modifications cut the mounting area on the circuit board by 35% against
single-function devices (potential reduction associated with general
application products; Toshiba data.), making it possible to realize more
compact products while maintaining the standard functions of mobile


Mobile products using lithium-ion batteries such as cellular phones and
