16 Channel LED Drivers

Precision Drive^TM Constant Current Drivers

The PrecisionDrive^TM LED drivers are dedicated for LED displays. All the series exploits state-of-the-art PrecisionDrive^TM  technology to enhance the output characteristics and accuracy. The PrecisionDrive^TM series features +/- 1.5% current accuracy among output ports within a single driver IC, and +/- 1.5% deviation among lots of driver ICs. The current varied with the LED forward voltage change is confined to 0.1% per volt. The current varied with supply voltage change and ambient temperature change is also restricted to 1%

Multi Function LED Drivers

Share-I-O^TM technology features pin compatibility. By means of the Share-I-O^TM technique, additional functions can be added to LED drivers without adding any extra pins in the package and without changing the printed circuit board originally designed for conventional LED drivers

S-PWM Series (PrecisionDrive^TM/Share-I-O^TM)

The Scrambled-PWM(S-PWM) technology enchances Pulse Width Modulation by scrambling the image into several sub-imgaes with the same colour quality. The enhancement equivalently increases the visual refresh rate. When building a 16-bit gray scale LED display, S-PWM avoids the flickers and improves the fidelity
