TOKYO -- February 15, 2013

Toshiba Corporation (TOKYO:6502) today announced that it has launched an LED
driver for LED display and illumination equipment that can illuminate 8
RGB-LEDs with a single IC. Samples are available now and mass production is
scheduled for March 2013.

The new product, TB62D612FTG, supports common anode LED control systems and is
embedded with a 7-bit PWM gray controller and a 24ch constant-current driver.
The constant-current circuit is divided into 3 blocks of 8chs. The electric
current of each block can be configured individually by an external resistor,
making it ideal for driving RGB-LEDs. Additionally, the address of the driver
IC can be set with 3 ID terminals and up to 64 ICs can be controlled
individually. PWM gray level and address selection is configured by an address
control interface, supporting simpler wiring that saves space on the circuit
board. A Toshiba developed circuit to counteract aerial discharge is used to
improve noise characteristics.

Key Features
1.  Supports 24ch × 40mA (maximum) high power current
2.   Achieves simplified board wiring (Address-control, use of small package)
3.   Able to individually control 64 ICs (max.) by ID configuration
