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 1.0H 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 applications.
