Product Description
IW7039-00-QFN4 Integrated Circuit Chip 32-Channel LED Back Lighting Driver QFN48
Product Overview
The IW7039-00-QFN4 is a high-precision, 32-channel LED backlighting driver with integrated current sinks designed for High Dynamic Range (HDR) LCD displays. This advanced driver incorporates 32 precision current sinks with digital control technology to enhance brightness control in direct backlit HDR displays. The digital control block utilizes BroadLED™ adaptive switch technology, optimizing thermal performance by regulating voltage drop across each LED string while enabling precision matching with unbinned LEDs.
