ISL97673IRZ - Renesas Electronics

Description: 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 v
