LP8555 Datasheet (Texas Instruments) - High-Efficiency LED Backlight Driver

LP8555, High-Efficiency LED Backlight Driver

The LP8555 is a high efficiency LED driver with integrated dual DC-DC boost converters.

It has 12 high-precision current sinks that can be controlled by a PWM input signal, an I2C master, or both.

Dual-boost configuration of LP8555 shares the load to two inductors and allows thinner overall solution
