32-Channel Internal Current Sink LED

Backlighting Driver

General Description

The iW7039 is a 32-channel, internal current sink, high precision, LED backlighting driver for high

dynamic range (HDR) LCD TVs, monitors and notebook displays. The device combines adaptive

DC/DC feedback control with Dialog’s BroadLED™ digital adaptive switch mode technology to

enable best system efficiency and thermal performance.

The iW7039 integrates the ability to use either analog or digital dimming methods in one device. With

a 10-bit/11-bit global or individual channel analog dimming and 12-bit PWM digital dimming, the

device improved contrast ratio in HDR displays. The current sinks can drive up to 66mA per channel

and have very tightly controlled current accuracy.

A full array or protection circuits are integrated, including built-in LED open/short detection, over

temperature protection and protection during both start-up and normal operation.
