G2546BR41U

The G2546B is a high-efficiency 4-channel WLED driver. It is designed for LCD panel which employs a WLED array as the lighting source. The G2546B has a wide input voltage range from 2.5V to 24V with an integrated boost converter. It drives 4 strings in parallel and supports up to 12 pieces of LEDs per string. The current of each string is adjustable from 6mA to 30mA. In addition, G2546B is integrated with 43V/2.0A 0.25 power MOSFET, and the boost driver automatically adjusts its output voltage to optimize the WLED forward voltage for better efficiency. Moreover, the internal sink current between each channel can reach a typical of ±1.5% current mismatching for excellent brightness uniformity.
