6-Channel SMBus or PWM Dimming LED Driver with Phase Shift Control
DATASHEET
FN7633 Rev.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.
