00 Sep 12, 2017 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.
The ISL97676 compensates for non-uniformity of the forward voltage drops in the LED strings with its 6 voltage controlled-current source channels.
Its headroom control monitors the highest LED forward voltage string for output regulation, to minimize the voltage headroom and power loss in the typical multi-string operation.
Intersil offers two PWM Dimming modes.
In the first mode, the ISL97676 digitizes the incoming PWM signal and provides 8-bit dimming.
The PWM frequency is set by a resistor providing dimming frequency between 100Hz to 30kHz.
The second mode offe...
