It features a high-performance boost converter, six channel current sink with 3% current matching and accuracy, and PWM brightness dimming control. The boost converter automatically provides the regulated output voltage for the WLED backlight without the need to calculate the output for different LED types. It also integrates a 50V NFET that provides high output power. The 6-channel current sink is ideal for constant current driving, and, well matched less than 3% (typical). To set the maximum driving current, the ISET pin is used to determine reference current. Each channel of the current sink is set to 58 times of this reference current. A PWM pin can be used for PWM dimming. The G5967 provides man...
