6-channel, internal current sinks LED driver with integrated boost controller

The iW7016 is a 6-channel LED backlight driver designed to deliver better screen performance and lower cost in next-generation 2D and 3D LCD TVs. It offers a highly integrated feature set, including a DC-to-DC boost controller with 10V gate drive, high-voltage current sinks, and Dialog’s patentedBroadLED™数字电流调节技术，消除了昂贵的LED封装的需要。

iW7016提供9V至36V的宽输入电压范围，并采用移相单独PWM调光以减少运动模糊；8位模拟调光；以及混合调光。

全面的调光模式使PWM输出位置和占空比的精确控制，提供最大的灵活性，以支持两种模式的缓速器和快门玻璃3D电视技术，以及2D电视，只有一个IC。
