LED Drivers

Related Information

Toshiba offers LED display drivers and LED backlight/lighting drivers for a wide range of applications.

The Toshiba LED display drivers embody innovative, proprietary solutions and are designed to drive large, full-color LED panels and support features such as very high-speed 8-16 channels with up to 16-bit of PWM grey scale adjustment, open circuit detection (OCD) and output short-circuit detection (OSD), which communicates status to the controller through a serial interface.

Toshiba LED Backlight Drivers are ideal for various sizes of LCD backlight applications such as smartphones, tablet computers, monitors and TVs. These drivers feature high efficiency with low-power consumption in small and thermally enhanced packages and comprehensive security features. Most of the LED backlight drivers can also be used in 2W to 60W DC-DC LED lighting applications.

Toshiba TC62D722/TC62D723 Display driver
The Toshiba TC62D722/TC62D723 Display driver is a 16 channel LED driver with 16-bit PWM dimming and 8-bit gain control
  • LED billboard (high-speed LED control of sub-pixel images)
  • LED signage (low-speed LED control for in illuminating signs)
  • Special-purpose LED lighting (aquarium lighting, indoor plant lighting, and etc.)
  • LED mood lighting
  • LED backlight with local dimming (dynamic backlight allows LCD to achieve superb contrast ratio, power savings, and blur-free image for high-end film studio monitor, medical x-ray monitor and graphic design grade monitor, and etc.)
  • 0.13 nm analog process enables this device to achieve world-class integrated MOSFET on-resistance (Ron) per unit area performance and significantly shrink the silicon geometry.
  • Highly efficient, compact and cost competitive to comparable products in the industry.
  • High current (90mA) driving capability (40-80mA).
  • 16-bit PWM dimming provides maximum gray scale level adjustment for each channel independently as well as 8-bit peak current adjustment for all channels.
  • PWM dimming level can be extremely low (as short as 25ns pulse).
  • Divisional PWM output function repeats PWM dimming 128 times within a dimming cycle providing flicker free images at very low duty cycles.
  • TC62D723 offers smallest QFN24 4x4mm2  over competition’s QFN24 5x5mm2 counterpart
  • Available stand-by-mode: Extremely low-power consumption (less than 1uA as the quiescent consumption current)
