Description: High-Efficiency LED Backlight Driver

Features

* which make it possible to detect LED outputs with open or short fault. As well low input voltage and boost over-current conditions are monitored and chip is turned off in case of these events. Thermal de-rating function prevents overheating of the device by reducing backlight brightness when set tem

Applications

* needing higher output voltage 2.7V
* 22V input voltage range to support 1x…5x cell LiIon batteries Programmable PWM resolution
* 8 to 13 true bit (steady state)
* Additional 1 to 3 bits using dithering during brightness changes I2C and PWM brightness control PWM output freque
