Boost WLED Driver for Backlights

General Description The G5966L/G5966 is a 6-channel boost WLED driver for backlight applications. It features a high-performance boost converter, six channel current sink with 3% cur-rent 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. The switching frequency is 1MHz. It also integrates a 40V 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 1000 times of this reference cur-rent. A PWM pin can be used for PWM dimming.

The G5966L/G5966 provides many protection schemes to avoid any abnormal operation. Over current protection is designed to protect internal NFET. It also provides over voltage and over temperature protection. The G5966L can detect open or short LED and offer pro-tections.

The G5966L/G5966 is available in a 16-pin 3x3mm TQFN package.
