General Description

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 0.25Ω 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.

G2546B supports 3 dimming methods including DCmode, Mixed-mode and Direct PWM-mode that have been widely adopted in nowadays NB display application.
