描述

The iW7027 is a 16-channel LED backlight driver that enhances TV picture quality and reduces BOM cost for 2D and 3D LCD TVs. It uses external LED current sinks and up to two external DC/DC converters (boost, buck, LLC, etc.) for the LED driver to enable easy current and voltage scaling. By integrating Renesas' patented BroadLED™ technology, enabling a unique 2-pin LED open/short sensing technology to protect the external current sinks, the iW7027 eliminates the need for high voltage sensing components and reduces the required pin count, resulting in a smaller, lower-cost package. The BroadLED technology also enables the use of loosely binned LED arrays, further reducing the total BOM cost.

Renesas' patented AnyMode™ dimming offers comprehensive, simple and flexible options to improve LED TV picture quality. It allows continuous PWM signals or burst PWM signals that are fully synchronized to the video frame at the same or higher frequency. The PWM duty cycle can be updated in each video frame and with user-configurable tail or head delays. This provides more options to reduce motion blur and improve the contrast ratio. A built-in phase-locked loop (PLL ) further ensures jitter-free operation even with a noisy VSYNC signal.
