6-Channel LED Driver with Phase Shift Control

The ISL97676 is an LED driver that drives six channels of LED
current for TFT-Display. The ISL97676 drives six channels of LED to
support 78 LEDs from 4.5V to 26V or 48 LEDs from a boost supply
of 2.7V to 26V and a separate 5V bias supply on the ISL97676 VIN
pin.
