3.
00 Sep 19, 2017 The ISL97673 is a 6-Channel 45V dual dimming capable LED driver that can be used with either SMBus/I2C or PWM signal for dimming control.
The ISL97673 drives 6 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 on the ISL97673 VIN pin.
The ISL97673 compensates for non-uniformity of the forward voltage drops in the LED strings with its six 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 a typical multi-string operation.
The ISL97673 features optional channel phase shift control to minimize the input, output ripple characteristics, and load transients, as well as spreading the light...
