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 patented BroadLED™ digital current regulation technology to eliminate the need for costly LED binning.

The iW7016 offers a broad input voltage range of 9V to 36V and incorporates phase shifted individual PWM dimming to reduce motion blur; 8-bit analog dimming; and hybrid dimming.

The comprehensive dimming modes enable precise control of the PWM output position and duty cycle, providing maximum flexibility to support both patterned retarder and shutter glass 3D TV technologies, as well as 2D TV with just one IC.
