Intersil offers a broad portfolio of display ICs
including gamma buffers, DC-DC regulators, and digitally
controlled potentiometers (DCPs) that provide a complete
analog solution for high performance LCD displays.
Combined, these products provide the analog supply voltage, VCOM
reference, voltage-on and voltage-off bias voltages, and the
gamma reference voltages that feed the column drivers in LCD
displays. Intersil's DC-DC regulators power the low voltage
digital ICs used in LCD displays and DCPs control the LCD
contrast and brightness.

ISL97671 6-Ch 45V/40mA per ch LED Driver
Parts & Ordering Information:
ISL97671
The ISL97671 is one of the industry best LED drivers that offers high integration, performance, and flexibility in a small form factor. The ISL97671 offers flexible SMBus/I2C or PWM controlled dimming. It features excellent ch-to-ch current matching. The driver provides optional channel phase shift control to minimize the input, output ripple characteristics and load transients as well as spreading the light output to help reduce the video and audio interference from the backlight driver operation. In addition, the PWM dimming linearity achieves an impressive 0.4% at 30kHz or 0.007% at 200Hz that such performance can be utilized to extend battery run time for Tablet to Notebook PC applications.
