ISL97671A
6-Channel SMBus/I2C or PWM Dimming LED Driver with Phase Shift Control
FN7709 Rev.4.00 Sep 14, 2017
The ISL97671A 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 ISL97671A can drive six channels of LEDs from an input of 4.5V~26.5V to an output of up to 45V. It can also operate from an input as low as 3V to an output of up to 26.5V in bootstrap configuration (refer to Figure 38 on page 26).
The ISL97671A features optional channel phase shift control to minimize the input/output ripple characteristics, and load transients to improve efficiency and eliminate audible noise.
The device can also be configured for Direct PWM Dimming with a minimum dimming duty cycle of 0.007% at 200Hz.
